great game, i loved it. the single player is amazing, it changed the whole way i play shooters, period. this game made me go for stealth and caution over brute force altogether. the coop is amazing as well. it's amazingly fun, it's just too bad it's not longer. the single player is incredebly rewarding and fun. i could spend hours just replaying levels, sneaking up on enemies and taking them with airfoil rounds. great game all in all, i should have never given it away. i just don't like that it wasn't longer, i'm really looking forward to double agent, can't wait to get it
