This game is still definitely on of the best co-op games made, by yourself its shite but as a team its insane,
there are now choices to be made, like in the frist mission you can choose whether to kill your contact of leave him, killing him is part of the mission, so you kinda decide what happens later in the game, but some people will give you unique gun and armour parts if you save them, and now you can hold enemies hostage while your parter ties them up
Loving it so far, o and at www.armyoftwo.com you can creat your own armour and masks, AWESOME!
so far 9/10
