I was utterly impressed by the amount of work that was put into this game, from animations to models, and gotta say - we love the SI armor concept you went with!
If you will look into any bug-fixing in the future, I suggest going a bit more easy on pickup accuracy - it was sometimes really challenging to pick up ammo from the floor. Not sure if it was planned, but NPCs do not walk unless they're being shot at (then, they start chasing you, which is fun)!
