@Oxy: You'r right - nothing special but funny.
And you're right with the camera code and the (currently missing) AI.
There are some other bugs (zombies walk through walls, light errors, ...), some are fixed already.

@OblivionDrake: just use one of them and don't mix them up. Maybe you have to copy the "d3dx9_30.dll" into the games directory but I'm not shure. Otherwise I can't help you with that now. Maybe a future version will run for you. Don't be to sad - it's nothing special as Oxy mentioned
