+## Setting up Xash3D FWGS in Qt Creator
+
+### Intro
+
+Most versions of Qt Creator support using `compile_commands.json` as a project
+file and Waf supports generating this file in a compliant format. In this
+tutorial we will leverage that features.
+
+The tutorial is written using Qt Creator 18.0, but I urge you to use whatever
+latest Qt Creator version is available, as it's often has important bug fixes.
+
+### Step 1. Configure the build.
+
+`compile_commands.json` file, as it can be guessed from it's name, contains
+every command used to invoke compiler during build. As the build process
+depends on the build configuration, we have to configure it first. I'm not
+going to get into details here, as basics of compiling Xash3D FWGS already
+explained in `README.md`, located in repository root.
+
+Save the configure step command somewhere, as it's going to be used later.
+
+### Step 2. Generate `compile_commands.json` file.
+
+Usually, this file is located in `build` directory after a successful build.
+However, it's also possible to generate it manually by running follow command:
+
+On *nix systems:
+
+```
+$ ./waf clangdb
+```
+
+Or on Windows:
+
+```
+> waf.bat clangdb
+```
+
+### Step 3. Load the project in Qt Creator.
+
+To do this, you need to be sure that `Compilation Databases` plugin is enabled.
+As it's considered experimental, it probably needs to be enabled manually. It
+can be done in `Help` -> `About Plugins...`. Locate it in `Build Systems`
+category, put the checkbox and press `OK`. The IDE will ask for restart, so do
+this.
+
+After IDE has been restarted, you can use `File` -> `Open File or Project...`.
+Navigate to Xash3D FWGS directory, then to `build` directory and select
+`compile_commands.json` file. If everything is done correctly, IDE will ask to
+set up the project. Press `Configure Project` button, as most options there are
+usually unapplicable to us.
+
+Next IDE will show project tree, however you might not see any files. This is
+happens as Qt Creator "thinks" our project root located in `build` directory.
+Thankfully it provides a way to override this. To fix it, click with right
+mouse button on the root of project tree (it's usually called something like
+`build [master]`) and select `Change Root Directory`. In opened window choose
+Xash3D FWGS repository root and press `OK`.
+
+### Step 4. Tell IDE how to build this project.
+
+Open `Projects` on the left menu and choose `Build Settings` tab. You should
+see an empty configuration for build and clean steps. Press on `Add Build Step`
+button and choose `Custom Process Step`.
+
+In created step you should see `Command`, `Arguments` and `Working Directory`.
+
+For the command, choose the Python executable. For arguments, use configure
+command for Waf from the first step. Working directory is usually set by IDE
+to `%{buildDir}`. You need to select the upper directory, where the `waf` is
+located. To save some time, it can be specified as `%{buildDir}/../`.
+
+Add another custom step, fill it with the same command and working directory.
+For arguments use `waf build`.
+
+Below you should see `Clean steps`. Create a clean step the same way, fill the
+arguments and working directory as usual, for arguments use `waf clean`.
+
+### Step 5. Tell IDE how to copy built binaries.
+
+Now select `Deploy Settings` tab. Press `Add Deploy Step` -> `Custom Process
+Step`. Again, same command and working directory. In arguments field type:
+`waf install --destdir="<here put where Xash binaries should be copied to>"`.
+
+### Step 6. Finally, set up Qt Creator to run the engine.
+
+Select the `Run Settings` tab. Below you might see familiar text fields:
+`Executable`, `Command line arguments` and `Working directory`.
+
+For working directory click on `Browse...` button and select the folder where
+Xash3D executable will be copied to, from previous step.
+
+For executable type `./xash3d` if you're on *nix or `xash3d.exe` if you're on
+Windows. The command line arguments are the same you use to run the engine. Can
+be empty as well, but I personally use `-dev 2 -log` for extra verbosity.
+
+### Outro
+
+At this moment, you should be able to press `Run` button, wait until build
+finishes and see running Xash3D FWGS. On Windows to use the debugger you might
+need the `CDB` debugger and appropriate `qtcreatorcdbext` binary for debugging
+32-bit applications and a separate for 64-bit, but that's left as an exercise
+for the reader and a potential improvement for this document.

-```
-if $ent_last_name == my_ent1_$name
-:(ent1 actions)
-if $ent_last_name == my_ent2_$name
-:(ent2 actions)
-```
-Note that scripting cannot be blocking. You cannot wait for server answer and continue. But you can use small scripts, connected with ent_last_cb command. The best usage is user interaction. You can add touch buttons to screen or call user command menu actions by callbacks.
-##  Server side
-
-To enable entity tools on server, set sv_enttools_enable to 1
-
-To change maximum number of entities, touched by ent_fire, change sv_enttools_maxfire to required number.
-
-To enable actions on players, set sv_enttools_players to 1.
-
-To enable entity tools for player by nickname, set sv_enttools_godplayer to nickname. Useful to temporary enable from rcon.
-
-To prevent crash on some actions, set host_mapdesign_fatal to 0

+## Lightmapped water
+
+Xash3D FWGS supports lightmapped water, as an extension. It adds three new cvars and new worldspawn key values.
+
+### For level designers:
+
+If you're a level designer and intend to make your level to have lightmapped water, you can put these keyvalues to worldspawn entity description (always first entity in entities list):
+
+| Key                    | Value   | Description |
+| ---------------------- | ------- | ----------- |
+| `_litwater`            | integer | Set to any non-zero value to enable lightmapped water. Overrides `gl_litwater_force` cvar value. |
+| `_litwater_minlight`   | integer | Minimal lightmap value water surface will receive. Helps to avoid too dark areas when water isn't properly lit. If not set, defaults to zero. |
+| `_litwater_scale`      | float   | Scales up lightmap value for water surfaces. If not set, defaults to 1.0. |
+
+### For players:
+
+Some of the maps already have computed lightmap for water surfaces and sometimes water has been properly lit but the support hasn't been declared by the level designer.
+
+As a player, you can enable it in `Video options` menu or through console with `gl_litwater_force` cvar. There are also `gl_litwater_minlight` and `gl_litwater_scale` cvars that function similar to keys above. The default values has been set to `192` and `1.25` respectively to slightly avoid issues with maps that wasn't intended to have lightmapped water.

+# Steam API Broker Protocol Specification
+
+## Overview
+
+Due to proprietary nature of Steamworks SDK, it cannot be run on same amount
+of platforms supported by Xash3D FWGS, neither we can link library directly due to
+GNU GPLv3 license. 
+
+However, here comes the broker, by running it (in trusted
+network, preferrably) on a machine that has Steam client installed, the
+engine can communicate with it, acquiring needed information to log-in into
+Steam protected multiplayer servers.
+
+## Key Characteristics
+
+Broker uses a simple TCP-based binary protocol with the following properties:
+
+- Single active session per connection: once a session is activated, the broker will reject all other TCP connections until the session is terminated.
+- All messages follow a consistent structure with a header, length, and payload: this is called a "frame".
+- Stateful interactions: commands affect the session state, and certain commands are only valid in specific states.
+- Numeric parameters are encoded in little-endian format for compatibility with majority of platforms.
+---
+
+## Frame Format
+
+All communication uses a fixed frame structure:
+
+| Field | Size | Type | Description |
+|-------|------|------|-------------|
+| Header | 4 bytes | ASCII | Frame start signature |
+| Length | 2 bytes | uint16_t (LE) | Size of payload in bytes |
+| Payload | N bytes | Binary | Command string or response data |
+
+**Notes**:
+- Header must be exactly `SBRK` (`53 42 52 4B` in hexadecimal form)
+- Maximum frame size: soft limit is 4096 bytes, hard limit is 65535 bytes (due to uint16_t usage)
+
+---
+
+## Session Lifecycle
+
+```
+┌──────────────┐
+│     IDLE     │ ← Initial state, accepts new TCP connections
+└──────────────┘
+       │ sb_gamedir
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Session established, rejecting all of other TCP connections
+└──────────────┘
+       │ sb_connect
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Client getting auth ticket to connect to game server
+└──────────────┘
+       │ sb_disconnect
+       ↓
+┌──────────────┐
+│     ...      │ ← Client announcing disconnect from game server, could connect somewhere again
+└──────────────┘
+       │ 
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Client shutting down game, terminating broker to reset Steam client state
+└──────────────┘
+       │ sb_terminate
+       ↓
+┌──────────────┐
+│  RESTARTING  │
+└──────────────┘
+```
+
+---
+
+## Commands
+
+All commands listed below are meant to be sent from client to broker as payload of a frame. The broker will parse the command string and respond accordingly.
+
+### Session activation
+
+Activates the session and signaling game startup.
+
+**Format**: `sb_gamedir <gamedir>`
+
+**Response**: None
+
+---
+
+### Authentication ticket request
+
+Requests authentication ticket for a game server.
+
+**Precondition**: Session must be active
+
+**Format**: `sb_connect <ip:port> <server_steamid> <secure> <challenge>`
+
+**Parameters**:
+
+| Name | Description |
+|------|------------------|
+| `<ip:port>` | Game server address (e.g., `127.0.0.1:27015`) |
+| `<server_steamid>` | Server SteamID |
+| `<secure>` | 0 = insecure, 1 = secure |
+| `<challenge>` | Random value for reply prevention |
+
+
+**Response Format**:
+
+| Field | Size | Type | Description |
+|-------|------|------|-------------|
+| Header | 11 bytes | string | `"sb_connect\n"` |
+| Challenge | 4 bytes | int32_t (LE) | Echo of challenge from request |
+| SteamID | 8 bytes | uint64_t (LE) | Client SteamID from configuration |
+| Size | 4 bytes | uint32_t (LE) | Length of ticket in bytes |
+| Ticket | N bytes | - | Authentication ticket data |
+
+---
+
+### Server disconnection announcement
+
+Notifies broker of disconnection from game server.
+
+**Precondition**: Session must be active
+
+**Format**: `sb_disconnect <ip:port> <challenge>`
+
+**Response**: None
+
+---
+
+### Session termination
+
+Signaling game shutdown to broker and resetting Steam client state.
+
+**Format**: `sb_terminate`
+
+**Response**: None

+# XRCON Protocol Specification
+
+## Overview
+
+XRCON is a TCP-based remote console protocol implemented as a server within the engine. It provides an alternative to the legacy RCON (which operates over UDP as out-of-band packets). XRCON uses a framed binary protocol over a single persistent TCP connection, accepting at most one client at a time.
+
+Key characteristics:
+
+- Based on TCP (stream-oriented, reliable)
+- Default port is 27000
+- Maximum only one concurrent client
+- Binary framed protocol with a 12-byte header + variable-length payload
+
+
+
+## Configuration
+
+The XRCON server is controlled by two configuration variables, both restricted to privileged users:
+
+| Variable | Default | Description |
+|---|---|---|
+| `xrcon_enable` | `0` (disabled) | Master switch; when enabled, the server starts listening for connections |
+| `xrcon_address` | `127.0.0.1:27000` | Bind address and port; supports both IPv4 and IPv6. Changing this at runtime triggers a XRCON server restart (stop + rebind) |
+
+By default, XRCON binds only to localhost (`127.0.0.1`), providing a degree of access control. The server will not start listening until explicitly enabled.
+
+
+
+## Frame Format
+
+All XRCON messages are encapsulated in a framed binary format. Each frame consists of a fixed 12-byte header followed by a variable-length payload.
+
+### Header (12 bytes)
+
+| Offset | Size | Field | Description |
+|---|---|---|---|
+| 0 | 4 | Type | 4-character message type string (null-terminated, occupies 5 bytes in the structure but the 5th byte is padding) |
+| 4 | 4 | Version | Protocol version (32-bit unsigned integer, network byte order) |
+| 8 | 2 | Length | Total frame length in bytes, including the header (16-bit unsigned integer, network byte order) |
+| 10 | 2 | Handle | Handle or sequence number (16-bit unsigned integer, network byte order; currently always zero) |
+
+
+### Protocol Version
+
+The current protocol version is `0x000000D4` (212 decimal). The server also accepts `0x00D40000` for compatibility with certain third-party clients (e.g., CS2RemoteConsole).
+
+### Maximum Frame Size
+
+- Maximum payload per frame: 4096 bytes
+- Maximum total packet size (header + payload): approximately 4136 bytes
+- Receive buffer size: 4096 + 64 bytes
+- Transmit buffer size: 16384 bytes (4 × maximum frame size)
+
+### Byte Order
+
+Multi-byte integer fields (version, length, handle) are transmitted in **network byte order** (big-endian).
+
+
+
+## Message Types
+
+| Type | Direction | Description |
+|---|---|---|
+| `CMND` | Client → Server | Execute a console command |
+| `PRNT` | Server → Client | Console output / print message |
+| `CHAN` | Server → Client | Channel list (channel metadata) |
+| `AINF` | Server → Client | Application / server info |
+| `ADON` | Server → Client | Additional info / server name |
+
+### CMND — Client Command
+
+**Direction**: Client → Server
+
+Sent by the client to execute a console command on the server.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CMND"`, version, length, handle |
+| Payload | Variable | Raw command string (null-terminated) |
+
+The command string is injected into the engine's command buffer for execution. There is **no authentication** — any connected client may execute arbitrary commands.
+
+### PRNT — Server Print
+
+**Direction**: Server → Client
+
+Sent by the server to stream console output to the connected client.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"PRNT"`, version, length, handle |
+| Channel ID | 4 bytes | Channel identifier (unsigned 32-bit integer; always 0 for "Console") |
+| Padding | 20 bytes | Reserved (5 × 32-bit unsigned integers, all zero) |
+| Red | 1 byte | Red color component (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha / opacity component (always 255) |
+| Text | Variable | The console output text (up to 4096 bytes) |
+
+
+### CHAN — Channel List
+
+**Direction**: Server → Client
+
+Sent by the server during the initial handshake (and potentially later) to describe the available console output channels.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CHAN"`, version, length, handle |
+| Channel Count | 2 bytes | Number of channel records (unsigned 16-bit integer; always 1) |
+
+Each channel record (58 bytes):
+
+| Field | Size | Description |
+|---|---|---|
+| Channel ID | 4 bytes | Unique channel identifier (unsigned 32-bit integer; always 0) |
+| Unknown 1 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Unknown 2 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Default Verbosity | 4 bytes | Default verbosity level (unsigned 32-bit integer; always 5) |
+| Current Verbosity | 4 bytes | Current verbosity level (unsigned 32-bit integer; always 5) |
+| Red | 1 byte | Red color component for the channel (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha component (always 255) |
+| Name | 34 bytes | Channel name string, null-padded (always `"Console"`) |
+
+Total payload size for this frame: 2 + 58 = 60 bytes.
+
+### AINF — Application Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after a client connects, before `ADON` and `CHAN`.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"AINF"`, version, length, handle |
+| Payload | 77 bytes | All zeros (placeholder / reserved for structured application information) |
+
+This packet currently serves as a placeholder and contains no meaningful data. It may be extended in future versions to carry structured metadata about the server application.
+
+### ADON — Additional Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after `AINF` during the connection handshake.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"ADON"`, version, length, handle |
+| Unknown | 2 bytes | Reserved (unsigned 16-bit integer; always 0) |
+| Name Length | 2 bytes | Length of the name string (unsigned 16-bit integer) |
+| Name | Variable | Server name / identifier string (e.g., `"HLDS"`) |
+
+This packet carries the server application name, which is a short string identifying the server type (e.g., `"HLDS"` for Half-Life Dedicated Server).
+
+
+
+## Security
+
+XRCON has **no built-in authentication or encryption**. There is no password validation or transport-layer security. Any client that can establish a TCP connection to the XRCON port has full command execution access to the engine console.
+
+The only security measures are:
+
+1. **Default localhost binding**: The server binds to `127.0.0.1` by default, accepting connections only from the local machine.
+2. **Disabled by default**: The `xrcon_enable` variable defaults to `0`, so the server does not listen unless explicitly enabled.
+3. **Privileged variables**: Both configuration variables are restricted to privileged users and cannot be modified through unprivileged console commands or external access.
+
+
+
+## Comparison with Legacy RCON
+
+| Feature | XRCON | Legacy RCON |
+|---|---|---|
+| Transport | TCP (stream) | UDP (datagram, out-of-band) |
+| Port | Configurable, default 27000 | Game port (default 27015) |
+| Framing | Binary frame header | Plain text over UDP |
+| Authentication | None | Password-based |
+| Max clients | 1 | Multiple |
+| Interaction format | Full console access | Request-response only for submitted command |
+| Supported environments | Client and server | Server only |

+solved along with better compatibility with GoldSrc behavior, but may be not - we don't know logic behind this fake client checks.

+# NAT bypass feature in Xash3D FWGS
+Since IPv6 not as widespread as we would like, NAT (Network Address Translation) still being actively used by many internet service providers in an attempts to
+mitigate IPv4 addresses exhaustion. In short, they uses one IPv4 address and doing some tricks with ports to represent many other users behind this address.
+
+But this leads to a problem for users: they cannot accept direct
+incoming connections anymore. This means that if you are behind provider's NAT and will try to setup Xash3D FWGS server - nobody will be able to connect to it,
+and the server will not show up in servers public list.
+
+## Is it possible to avoid this problem?
+In most cases, it is possible to bypass NAT with UDP hole punching, and Xash3D FWGS uses this method too. But this method is not 100% guaranteed to work - it depends
+on NAT configurations on both server and client side, and there is no way to control it.
+
+First of all, server should not be behind symmetric NAT. You can check your NAT type on [this page](https://www.checkmynat.com/).
+If you get "Symmetric NAT" result in this test, that means you cannot setup publicly available server with internet connection that you are using.
+
+Here is more detailed scheme of different NAT types compatibility, it explains are users with different NAT types can connect to each other or not.
+Client NAT type on rows, server NAT type on columns:
+
+| *NAT Type*           | Full Cone | Restricted Cone | Port Restricted Cone | Symmetric |
+| -------------------- | --------- | --------------- | -------------------- | --------- |
+| Full Cone            | ✔️        | ✔️              | ✔️                    | ✔️        | 
+| Restricted Cone      | ✔️        | ✔️              | ✔️                    | ✔️        |
+| Port Restricted Cone | ✔️        | ✔️              | ✔️                    | ❌        |
+| Symmetric            | ✔️        | ✔️              | ❌                   | ❌        |
+
+## How to use NAT bypass feature?
+If you are starting server within the game, you need to enable option "*Use NAT Bypass instead of direct mode*" in bottom left corner of screen.
+
+If you are starting dedicated server, you should add console variable `sv_nat 1` to server.cfg file, or add `+sv_nat 1` to server startup parameters.
+
+If you need to connect to server behind NAT, there is separate tab named *NAT* for such servers in server browser. Note that it is useless to add NAT server to favorites,
+or somehow trying manually to store it, because it has changing address and port.

+# Xash3D FWGS protocol support
+
+Xash3D FWGS currently supports four network protocols:
+* Version 49, introduced in Xash3D in around 2018.
+* Version 48, used in Xash3D FWGS 0.19 and earlier. Deprecated and to be removed in the future.
+* GoldSrc version 48, used in current GoldSource version.
+* Quake version 15, only used for demo playback for Quake Wrapper mod.
+
+On the server side, we only support Xash3D 49 protocol, but bugcomp `gsmrf` mode can convert GoldSrc 48 messages into Xash3D 49 on the fly, for some mods that directly write engine internal messages.
+
+In the following documents we will only cover version 49, as everything else is either not Xash3D specific or deprecated.

+# Xash3D 49 connectionless protocol
+
+Connectionless protocol defines four common message sources and destinations, they can be:
+* `S` for Server
+* `C` for Client
+* `M` for Master
+* `A` for Anything else
+
+All connectionless packets have `\xff\xff\xff\xff` (32-bit integer set to all ones) in it's header. Let's go through each of possible direction in this document.

+## Any
+
+### Any to Any
+
+#### `A2A_PING` and `A2A_GOLDSRC_PING`
+
+Simple ping message.
+* Request, in ASCII: `ping` or `i` in GoldSrc format
+* Response is always `A2A_ACK` or `A2A_GOLDSRC_ACK`
+
+#### `A2A_ACK` and `A2A_GOLDSRC_ACK`
+
+Simple ack message.
+* Request, in ASCII: `ack` or `j` in GoldSrc format
+* Response: none
+
+#### Deprecated queries
+
+These text-based Xash protocol queries are deprecated in favor of [GoldSrc server queries](#goldsrc-server-queries), which Xash3D FWGS servers implement as well. New implementations must not send them. The server still responds to `A2A_INFO` for compatibility with older clients, `A2A_NETINFO` is not handled anymore.
+
+##### `A2A_NETINFO`
+
+Used to implement Half-Life's NetAPI. 
+* Request message, in ASCII: `netinfo <version> <context> <request_id>`
+  - `version` must be 49, as text.
+  - `context` can be any 32-bit signed integer value, encoded as text.
+  - `request_id` see `common/net_api.h`
+
+* Response message, in ASCII: `netinfo <context> <request_id> <response>`
+  - `context` same as in request.
+  - `request_id` same as in request.
+  - `response` is server's response, depending on request type. Always encoded as Quake info string.
+
+Possible requests and response formats:
+* Request ID `1` will make server respond with empty response string. 
+* Request ID `2` makes server respond with all server game rule cvars where the key is cvar name and the value is cvar value. One additional key `rules` with total amount of cvars is added.
+* Request ID `3` makes server respond with players list, where:
+  - `p<id>name` is set to player's name
+  - `p<id>frags` is set to player's kill count
+  - `p<id>time` is set to player's total play time
+  - `players` is total player's list.
+  - Alternatively, it can respond with `neterror` set to `forbidden` if server does not wish to expose it's player list.
+* Request ID `4` makes server to respond with common game details:
+  - `hostname` is server's name
+  - `gamedir` is game directory name
+  - `current` is total player count
+  - `max` is max players limit
+  - `map` is server's current level
+* On any other server will respond with `neterror` set to `undefined`
+* If protocol version doesn't match, server responds with `neterror` set to `protocol`
+
+##### `A2A_INFO`
+
+Used to request server's details.
+* Request message, in ASCII: `info <version>`
+  - `version` must be 49, as text
+* Response message, in ASCII: `info\n<response>`
+  - `response` is Quake info string, otherwise it's an error message.
+
+* Response info string format:
+  - `p` is set to protocol version (FWGS extension)
+  - `map` is server's current level
+  - `dm` set to 1 if current game mode is deathmatch otherwise 0
+  - `team` set to 1 if current game mode includes teamplay otherwise 0
+  - `coop` set to 1 if current game mode is cooperative otherwise 0
+  - `numcl` is total player count
+  - `maxcl` is max players limit
+  - `gamedir` is game directory name
+  - `password` set to 1 if server is protected with password otherwise 0
+  - `host` is server's name
+
+### Any to Client
+
+#### `A2C_PRINT` and `A2C_GOLDSRC_PRINT`
+
+Simple print message.
+* Header: `\xff\xff\xff\xff`
+* Request, in ASCII: `print <message>` or `l<message>` in GoldSrc format.
+* Response: none
+
+### Any to Server and Server to Any
+
+#### GoldSrc server queries
+
+These match Source Engine Query messages used in GoldSrc and Source engine and implemented for compatibility with existing server browsers and monitoring tools. The client uses them to query GoldSrc servers in the server browser, and as text-based Xash protocol queries are [deprecated](#deprecated-queries), it will use them to query Xash servers as well. Read documentation for them on VDC: https://developer.valvesoftware.com/wiki/Server_queries
+
+Unlike other connectionless messages these are binary: integers are little-endian, floats are 32-bit IEEE 754 and strings are null-terminated.
+
+`A2S_GOLDSRC_PLAYERS` and `A2S_GOLDSRC_RULES` requests carry a 32-bit challenge, `A2S_GOLDSRC_INFO` may have one appended after the query string. When no challenge is known yet, `\xff\xff\xff\xff` is sent in it's place. The server may answer with a challenge instead of the data: byte `A` (`0x41`) followed by a 32-bit challenge value, 9 bytes total with the header. The request is then repeated with the received challenge. Don't confuse this message with textual `S2C_GOLDSRC_CHALLENGE` used during connection, they only share the first byte.
+
+Responses that don't fit into a single packet (usually rules) come from GoldSrc servers split into fragments. Such packets start with `\xfe\xff\xff\xff` instead of `\xff\xff\xff\xff`, followed by a 32-bit sequence number, same in all fragments of one response, and a byte with total fragment count in the lower 4 bits and this fragment's index in the upper 4 bits. Fragment payloads concatenated in index order form a normal `\xff\xff\xff\xff` message. Xash servers never split query responses and send them as single datagrams.
+
+#### `A2S_GOLDSRC_INFO`
+
+Used to request server's details.
+
+* Request: `TSource Engine Query\0`, optionally followed by a 32-bit challenge. Xash servers ignore it.
+* Response: byte `I` (`S2A_GOLDSRC_INFO`), followed by:
+  - byte: protocol version, 48 on GoldSrc, 49 on Xash3D FWGS
+  - string: server's name
+  - string: server's current level
+  - string: game directory name
+  - string: game description
+  - int16: Steam AppID, always 0 on Xash servers
+  - byte: total player count, bots included
+  - byte: max players limit
+  - byte: bot count
+  - byte: server type, `d` for dedicated or `l` for listen server
+  - byte: server's operating system, `w` for Windows, `l` for Linux, `m` for macOS
+  - byte: set to 1 if server is protected with password otherwise 0
+  - byte: set to 1 if server is VAC secured, Xash servers put the `secure` value from gameinfo here
+  - string: server's version
+
+Same as the Source engine response format but without the extra data flag and its fields.
+
+Legacy GoldSrc servers respond with the obsolete `m` format (`S2A_GOLDSRC_LEGACY_INFO`) instead, see VDC for its layout. Xash servers never send it but the client understands it and assumes protocol 48.
+
+#### `A2S_GOLDSRC_PLAYERS`
+
+Used to request server's player list.
+
+* Request: byte `U` (`0x55`), then a 32-bit challenge.
+* Response: byte `D` (`S2A_GOLDSRC_PLAYERS`), followed by a byte with total player count, then for each player:
+  - byte: player's index. Xash servers send sequential indexes starting from 0, GoldSrc servers always send 0 here.
+  - string: player's name
+  - int32: player's kill count
+  - float: time in seconds the player is connected, -1.0 for bots on Xash servers
+
+Xash server doesn't respond at all if the player list is empty, the server is protected with password or exposing the player list is disabled with `sv_expose_player_list` cvar.
+
+#### `A2S_GOLDSRC_RULES`
+
+Used to request server's game rules.
+
+* Request: byte `V` (`0x56`), then a 32-bit challenge.
+* Response: byte `E` (`S2A_GOLDSRC_RULES`), followed by an int16 with total rule count, then rule name and rule value strings for each.
+
+Only server cvars (`FCVAR_SERVER`) are sent. Values of protected cvars (`FCVAR_PROTECTED`) are replaced with `1` if the value is set otherwise `0`. If there are no cvars to expose, server doesn't respond at all.
+
+### Any to Master
+
+#### `S2M_SCAN_REQUEST`
+
+* Request: `1<region><IP:Port>\0<info>`
+  - Format of this message is loosely based on https://developer.valvesoftware.com/wiki/Master_Server_Query_Protocol
+  - `info` however adds few additional fields:
+    - `clver` set to engine's version
+    - `nat` set to 1 to filter only servers behind NAT and tell master to notify servers about scan

+    - `buildnum` set to engine's build number
+    - `key` set to random 32-bit value formatted as hex, used to validate master responses
+* Response: `M2A_SERVERSLIST`
+
+### Master to Any

+#### `M2A_SERVERSLIST`
+
+* Request: `f\xff<key><reserved><IP:Port>...`
+  - `key` is random 32-bit value set in `S2M_SCAN_REQUEST`
+  - `reserved` is single reserved 8-bit byte
+  - Following is list of IP addresses in binary form: 6-bytes for IPv4 address + port and 18-bytes for IPv6 address + port
+  - If port is 0, it means the end of list, otherwise it's the last IP used for pagination (not implemented in Xash3D)
+* Response: client doesn't make response to master server but might request `A2S_GOLDSRC_INFO` from servers
+
+## Master and game server
+
+### Server to Master
+
+#### `S2M_HEARTBEAT`
+
+Used to update game server information on the master server.
+
+* Request: `q\xff<heartbeat challenge>`

+
+* Request: `\x62\x0a`
+* Response: none
+
+#### `S2M_INFO`
+
+Game server info response on `M2S_CHALLENGE`.

+    - `type` set to `d` for dedicated or `l` for listen server
+    - `password` set to `1` if server protected with password set otherwise `0`
+    - `os` always `w`
+    - `secure` always `0`
+    - `lan` always `0`
+    - `version` engine version
+    - `region` always `255`
+    - `product` same as `gamedir`
+    - `nat` set to `1` if server is behind NAT

+
+### Master to Server
+
+#### `M2S_CHALLENGE`
+
+Master's respoonse on game server's heartbeat message.
+
+* Request: `s<master challenge><heartbeat challenge>`
+  - `master challenge` contains 32-bit value, used in server response to prevent faked/forged source IP addresses.

+# Static HTTP server list
+
+Replacement for the UDP `S2M_SCAN_REQUEST` / `M2A_SERVERSLIST` exchange
+described in [02-connectionless.md](02-connectionless.md). Read-only HTTP,
+no NAT punching, no filtering or pagination in the request.
+
+## URL
+
+`xashcomm.lst` carries a base URL per source:
+
+```
+masterstatic http://master.example.org/server-list
+```
+
+The engine appends `/v1/servers/<gamedir>` and `GET`s the result. For
+`gamedir = valve`:
+
+```
+GET http://master.example.org/server-list/v1/servers/valve
+```
+
+Trailing slashes on the base URL are stripped. Multiple `masterstatic`
+lines are allowed; results are merged.
+
+The request is bare: no body, no auth, no cookies, no compressed encodings.
+Only the standard `User-Agent` is set. `POST` / `PUT` / `DELETE` are not
+used; servers register out of band.
+
+## Response
+
+UTF-8 text, parsed line by line. Each line is tokenized with
+`COM_ParseFileSafe` (whitespace separates, `//` and `#` start line
+comments, `"..."` quotes a token). Blank lines and comment-only lines
+are ignored. One directive per line:
+
+* `ip <address>` — Xash3D server (protocol 49).
+* `gs <address>` — GoldSrc server (protocol 48).
+
+`<address>` is parsed by `NET_StringToAdr` (`1.2.3.4:27015`,
+`[2001:db8::1]:27015`, hostnames). Port defaults to `27015`. Lines
+starting with an unknown directive are skipped entirely, so new keywords
+with any number of operands can be added without breaking older clients.
+
+`Content-Type` is not inspected, `text/plain; charset=utf-8` expected.
+
+### Example
+
+```
+# diffusion servers
+ip 192.0.2.10:27015
+ip [2001:db8::1]:27015
+gs 198.51.100.5:27015
+```
+
+A file with zero records is valid and represents an empty list.
+
+### Versioning
+
+The `/v1/` segment is fixed in this revision. A future protocol revision
+adds a sibling `/v2/...` resource without breaking older clients.
+
+## Client behaviour
+
+Each `ip` / `gs` record from the response triggers a probe to the listed
+address, identical to a server discovered through the UDP master. DNS
+errors, non-200 responses, and malformed bodies are reported to the
+console.
+
+## Server behaviour
+
+Any static HTTP server works. A typical setup is a periodic job that
+probes a set of known addresses and writes `v1/servers/<gamedir>`.

+# Touch controls configuring
+
+## Introduction
+
+Thanks to mittorn, we have the ability to fully customize the controls in Xash3D. The new config allows you to not only add and change control buttons, but also create custom menus. There is also a built-in visual editor available, which simplifies the customization process without the need for manual file editing.
+
+## Editor mode usage
+
+1. Launch Xash3D and start the game.
+2. To enter the edit mode, click on the gear icon (command `touch_enableedit`).
+3. In the edit mode, the grid is displayed. The number of cells can be changed with the command `touch_grid_count` (default is 50). The grid can be disabled with the command `touch_grid_enable 0`.
+
+*Touch controls layout editor*
+![](images/editor.jpg)
+
+*Touch profiles window*
+![](images/touch-profiles.jpg)
+
+*Touch buttons parameters window*
+![](images/touch-buttons.jpg)
+
+## Layout editor features
+
+* **Moving buttons**: click on a button, drag it to the desired location, and release.
+* **Resizing buttons**: place your first finger on the top left corner of the button, and use your second finger to resize it.
+* **Hiding/showing buttons**: select the button (it will turn red), then use the menu:
+    * **Close**: closes the editing mode (`touch_disableedit`).
+    * **Reset**: resets the button to its default values.
+    * **Hide/Show**: hides or shows the button (`touch_hide <name>` / `touch_show <name>`).
+
+## Working with configuration files / console
+
+All changes made in the visual editor are automatically saved to the touch profile file. The files are located in the `touch_profiles` folder inside game directory. The file name depends on the selected profile.
+
+### Common commands in configuration files
+
+```
+// Comment: lines starting with // are ignored.
+
+// Swipe zones for movement. Specify how far you need to swipe to speed up.
+// The default values ​​are set to be optimal for a small swipe to immediately walk quickly.
+touch_forwardzone "0.060000" ; touch_sidezone "0.060000"
+
+// Sensitivity settings (pitch - horizontal, yaw - vertical).
+touch_pitch ; touch_yaw
+
+// Grid settings (see above).
+touch_grid_count ; touch_grid_enable
+
+// Draws a border around the button.
+touch_set_stroke <thickness> <c> <v> <e> <t>
+(<r> - red; <g> - green; <b> - blue; <a> - alpha/transparency)
+
+// Show (1) or hide (0) client buttons.
+touch_setclientonly
+
+// Removes all buttons from the screen.
+touch_removeall
+
+// Shows all available buttons in the configuration file.
+touch_list
+
+// Saves the config after editing. You can specify a new file name.
+touch_config_file command.cfg
+```
+
+*The full list of buttons in the standard `touch.cfg` file, displayed in the console when using `touch_list`.*
+![](images/example2.jpg)
+
+
+## Adding new buttons
+
+To add a new button, use the console command:
+
+```
+touch_addbutton "digits" "touch/key_1.png" "toggle_digits" 0.340000 0.782222 0.400000 0.888889 255 255 255 100 0
+```
+
+### Parameters of `touch_addbutton` command
+
+| Parameter | Description |
+| --- | --- |
+| `"digits"` | Unique name of the button. |
+| `"touch/key_1.png"` | Path to the icon file (`.png` format). If the icon is not needed, leave `""`. |
+| `"toggle_digits"` | Command to execute after clicking (for example, `"buy"` for purchase). |
+| `0.340000` | X coordinate of the upper-left corner of the button. |
+| `0.782222` | Y coordinate of the upper-left corner of the button. |
+| `0.400000` | X coordinate of the lower-right corner of the button. |
+| `0.888889` | Y coordinate of the lower-right corner of the button. |
+| `255 255 255` | Button color in RGB format. |
+| `100` | Button transparency (0 - fully transparent, 255 - fully opaque). |
+| `0` | Flags (see next section). |
+
+## List of flags
+
+Flags define the behavior of the button. Their values ​​are powers of two:
+
+| Flag | Value | Description |
+| --- | --- | --- |
+| `TOUCH_FL_HIDE` | 1 | Hides the button (not displayed in the game, but visible in the editor). |
+| `TOUCH_FL_NOEDIT` | 2 | Disables editing of the button in the editor. |
+| `TOUCH_FL_CLIENT` | 4 | The button is client-side (not saved in the main control file). |
+| `TOUCH_FL_MP` | 8 | The button is displayed only in multiplayer. |
+| `TOUCH_FL_SP` | 16 | The button is displayed only in singleplayer. |
+| `TOUCH_FL_DEF_SHOW` | 32 | The button is always displayed on startup. |
+| `TOUCH_FL_DEF_HIDE` | 64 | The button is always hidden on startup. |
+| `TOUCH_FL_DRAW_ADDITIVE` | 128 | The button colors are added together in blend mode. |
+| `TOUCH_FL_STROKE` | 256 | Enables outline stroke around the button. |
+
+Flags can be combined by adding their values ​​together. For example, `5 = 1 + 4` is the combination of `TOUCH_FL_HIDE` and `TOUCH_FL_CLIENT` flags, which is a hidden client button.
+
+*In the image below, the `spray`, `scores`, `messagemode` buttons are displayed simultaneously with the flag 8 and `loadquick`, `savequick` with the flag 16, and each is displayed in the corresponding game mode.*
+![](images/example1.jpg)
+
+## Useful commands
+
+* `touch_hide <pattern>`: hides buttons by pattern.
+* `touch_setcommand`: changes the command bound to a button.
+* `touch_settexture`: quickly changes the button image.
+* `touch_setcolor`: sets the button color.
+* `touch_exportconfig`: exports the current configuration, including aspect ratio.
+
+## Usage examples
+
+* `touch_hide menu*` hides all buttons with names starting with `menu`.
+* `touch_setcolor "attack" 255 160 0 128` changes the color of the primary fire button from opaque white to translucent orange, similar to the color of the HUD in Half-Life.
+
+    *Result of executing this command*
+    ![](images/example3.jpg)
+
+* Example of adding a new button with a custom icon (the `lastinv` command is used - quick change between weapons)
+    ![](images/example4.jpg)
+
+    *View of this button in layout editor*
+    ![](images/example5.jpg)
+
+## Tips
+
+* To prevent the `look` and `move` buttons from interfering with editing other elements, place them before the others in the configuration file.
+* And vice versa, to make a button appear on top of others, place it at the end of the configuration file.
+* You can assign commands to buttons that change other buttons, see the previous section "Usage examples".
+* After editing each parameter of each individual button in the Touch Buttons section, do not forget to press Save, otherwise the applied parameters will not be saved.
+* To create your own icon for the button, you can use any graphics editor (for Android, Photo Editor by iudesk is suitable). Saving conditions:
+    * Image format - `.png` with transparency (e.g. alpha channel)
+    * Aspect ratio / size - 1:1 / 256x256
+    * Path to the icons location - `touch/gfx` inside game directory.

+# Xash3D FWGS Security Policy
+
+## Supported versions
+
+Because we don't have clear release cycle yet, support is only provided to the
+latest engine versions from `master` branch. You can use `host_ver` command in
+console to fetch detailed info about the engine build.
+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability in this project, it can be reported
+privately though `Security` tab on GitHub:
+https://github.com/FWGS/xash3d-fwgs/security
+
+Alternatively, you can report them publicly on the `Issues` tab:
+https://github.com/FWGS/xash3d-fwgs/issues
+
+In both cases, expect a reply within approximately a week.
