GitHub Org's stars

Welcome to the official ReHLDS GitHub organization! We maintain and develop a family of open-source projects aimed at improving and expanding the experience for Half-Life and Counter-Strike 1.6 dedicated servers. Our projects include reverse-engineered versions of key components, performance optimizations, and custom APIs to enhance modding capabilities.


📦 Our Projects

Project Name Description
ReHLDS
GitHub Release
GitHub Releases
An improved version of the original HLDS engine, containing many security fixes and performance optimizations. It provides a more stable and enhanced server environment with extended API support for mods and plugins, offering better security and efficiency.
ReGameDLL_CS
GitHub Release
GitHub Releases
More stable (than official) version of Counter-Strike 1.6 (also Counter-Strike: Condition Zero) game library (mp.dll) with extended API for mods and plugins, enhanced (and fixed).
ReAPI
GitHub Release
GitHub Releases
AMXModX module that provides ReHLDS, ReGameDLL, ReChecker, ReUnion, VoiceTranscoder APIs for use in AMXModX plugins development.
Metamod-R
GitHub Release
GitHub Releases
Optimized fork of Metamod for improved plugin management and compatibility on modern HLDS-based servers.
ReSemiclip
GitHub Release
GitHub Releases
Metamod plugin controls the ability to pass through players. The module Semiclip by joaquimandrade was used as a reference.
ReUnion
GitHub Release
GitHub Releases
Metamod plugin created to support compatibility with older versions of the game client protocol (protocol 47). It is an idea sequel of DProto with new functionality for server protection.
ReChecker
GitHub Release
GitHub Releases
Metamod plugin that gives the ability to check client files by their md5 hash.
ReVoice
GitHub Release
GitHub Releases
Metamod plugin that allows voice chat between non-steam and steam clients (for ReHLDS).
ReFreeLook
GitHub Release
GitHub Releases
AMXModX module allows spectator admins to use any camera modes, regardless of the value of `mp_forcecamera` or `mp_forcechasecam` (for ReGameDLL). It is an idea sequel of Admin Free Look by jim_yang.
LocalizeBugFix
GitHub Release
GitHub Releases
Metamod plugin that fixes localization issues in HLDS by preventing or removing invalid characters in text, ensuring clean and correct display of localized messages. Deprecated, was completely replaced by the SafeNameAndChat.
SafeNameAndChat
GitHub Release
GitHub Releases
Metamod plugin that replaces special characters in player names and chat messages to prevent bugs. It swaps certain characters with similar Unicode alternatives, removes non-printable characters, and trims spaces from the start and end of text for improved safety and consistency. Deprecated for ReHLDS since 2015
ReLocalizeBugFix
GitHub Release
GitHub Releases
An extension of LocalizeBugFix for ReHLDS, aimed at addressing localization-related bugs in the server, deprecated since 2015.
HitBox Tracker
GitHub Release
GitHub Releases
A development tool that aimed to demonstrate the true position of hitboxes calculated by the server in CS 1.6. However, it is now outdated (thanks to @Garey27 Hitbox Fixer module) due to inaccuracies in the hitbox position calculations within the display code.
