pretty good
Great job, the look and feel of the game is good. I just wish the camera locked the mouse, that would make camera movement a hell of a lot easier. The customizable controls are definitely a plus. Textures were nice, weapon models were pretty good. The heartbeat got pretty annoying after awhile, perhaps have that when the players health reaches like twenty five or something.
The desert eagle feels weaker than the shotgun, I didn't play long enough to get to the next weapons. Although, that does seem reasonable. The shotgun just needs a spreadshot effect, unless you intended for it to have slug rounds. I'd think that was acceptable when the guardian says that he sells silver bullets.
Great game, just work on that camera.
