What is Spearmint?

Spearmint is a heavily modified version of the Quake III Arena engine. Spearmint is directly based on ioquake3.

Some of the new features / changes:

Four player splitscreen support.
Bullet marks on doors and moving platforms.
Aspect correct wide screen FOV and HUD in Q3A.
Improved Bot AI.
Improved gamepad support.

Many modding improvements:

It's possible to do a lot more without modifying the engine. New networked variables can be added to players and game objects. A lot of code has been moved from the engine to the VMs such as setting up the player input sent to the server, a lot of the bot AI, and miscellaneous drawing for the console, chat input, etc. The UI VM has been merged into CGame for greater flexibility. There are new system calls for CGame and Game VMs and new shader keywords. The engine and gamecode have been split into separate repositories.

Spearmint is not compatible with Quake 3 mods (QVMs/DLLs) or replay demos.
