Great game, not so great camera controls.
The texture mapping and bump mapping looks good, but the graphics on the NPC's could be improved as they look more or less the same. The music gets a little annoying after a while because it starts to sound pining like its trying too hard to create a saddening atmosphere like that achieved to almost perfection in Fallout 3. But the radio stations help to provide variety and it doesn't really take away from the game.
The combat seems pretty solid so far, and the FPS animation looks great. Those iguanas scuttling around move quick! I've only scratched the surface of the game so far. Definitely looking forward to continue playing it!
