Boring game.
Constructive criticism time:
Try coming up with a story that isn't "Get files, kill people and 'the chief'" for one. If you want to have a game that's remembered, you should give it a better story.
Common sense works, too. If I'm standing around and the light above me is shot out, I'm not going to be standing there as if nothing happened. Likewise, if I put a bullet into someone's head, they shouldn't really be standing up anymore. Give penalties for using the gun.
Redundancy isn't that fun either. The whole game is "shoot lights, shoot cameras, crouch, kill people."
Lastly, the graphics. Not only are most of the things we see are straight objects (Using the circle tool, square tool, etc), but even the colors are bland and don't do any justice to the game. The 'night vision goggles' doesn't make sense either- why not have a green stream of light follow your mouse? If you're wearing night vision goggles in real life, everything that is in a ten-foot diameter around you don't start glowing green.
I'm doing my best to be nice about this, but damn, it's really bad.
