The open source port of Halo: Combat Evolved for Mac, Windows, and Linux.
Mac, Windows, and Linux each run the game’s own code, with a new layer in place of the Xbox hardware.
Your own copy
Bring your own copy of the game. The download has no game data. Put the Xbox maps in maps, and Custom Edition maps in custom_maps beside them.
Multiplayer
- Up to 128 players, and up to four on one screen.
- Windows, Linux, and Mac play together. On a local network they can play LAN.
- Peer-to-peer hosting, a server browser, and invite links.
- Online campaign co-op.
- Voice chat, and Custom Edition maps shared by the other players.
The game
- The Xbox look, until a setting says otherwise. Field of view and smooth motion are optional.
- Windows and Linux draw with OpenGL. The Mac build draws with Metal.
- Sound, input, and gamepads go through SDL3.
- On Mac, the app can update itself. On Linux and Windows, an update replaces the program files and keeps maps, saves, and
config.toml.
