If co-op games are you preference, then this is the game for you. p to four friends can join together and have lots of fun shooting and collecting xp and credits to boost your teams skills. The game is very responsive. Everything runs smoothly with no sticking or slowdown. Gorgeous graphics compliment the whole game. The only downside is, we completed the game in three days. It came as quite a shock to find we were going through the final credits. All in all a very good game, but a very short Fuse.
