More details

This repository contains Source Engine sources based on version 2007.

It is a place to share ideas on what to implement, gather people that want to work on the engine, and work on the source code.

If you find a bug or have an enhancement request, file an Issue.

Pull requests appreciated! However, the following things should be taken into consideration:

  • We want to keep the game as close as possible to the vanilla game, so instead of introducing new gameplay features, consider adding non-gameplay features, fixing bugs, improving performance and code quality
  • Major changes should be discussed before implementation

Be advised that this project is not sanctioned by Valve in any way – and they remain the copyright holders of all the original source code.
