Tier666TA is a bot AI modification focused on replay value. Bots can now move around just as pro players do. To play this mod, you need both Quake3 Arena and Team Arena installed on your PC.
The next version of Tier666(v4.0, not released yet as of 2012/1/18) guarantees a significant improvement of bot movement compared to the previous versions.
Bots can now use strafe tapping when dodging lightning gun or rail gun.
