I think I just had a flashgasm.
This game is amazing but can be extremely hard at times. I couldn't even beat chapter 2! It's impossible to kill the guards before they raise the alarms. The music is great and sounds like it came straight from a Metal Gear Solid game. The sound effects are great and the judgement you have to put into this game to determine who is the target is a great feature. Overall this is probably the best shooting game on Newgrounds.
