Sorry for the lack of updates recently, but we've been faced with a big decision. The walk on walls code, while quite impressive, is far too buggy to create an enjoyable game. The point is that at its current state its just not good enough leaving us with 3 possible decisions.
1. try to improve the code to a playable state.
2. Switch engines to Quake 3 and lose vehicles
3. Wait and hope for a release of the Quake 4 source code.
Unfortunatey, option 2 or 3 will probaly have to be taken. On the positive side, this might allow for a standalone release. I will keep you updated as this decision is made.
