Q3 Rally is a car driving and car combat Modification for OpenArena. It still works with Quake III Arena but design focus lies on OpenArena now. The most actual version is 1.33. The V1.4 release is on the way. Stay tuned.
A really nice and original idea. Add a racing mod to the Q3.
The problem present on this game could be the single player gaming, and some bugs presents on the maps and gameplay. So that is why mi final score is not too high.
Buth if you wanna get fun experimanting with this, play some races on DeFRaG maps (fully insane)
