The multiplayer is awsome and stays awsome for hours at a time!!
Even though the single player can get boring the multiplayer stays great. Then hundred or sop weapons to choose from gives you a wide selection of diversity whether your a hardcore sniper or a crazed auto rifleman there is a weopon screeming for you to use it. Multiplayer does have its draw backs though... it can be dificulpt to find a game sometimes bc higher level people boot noobs that join a game. YOu may have to try 3 games before you find some one that is going to let you polay in his room. Sometimes you will find your self in a room and everyone is a marksmen witch can be a hassell and take away from the game play (every 2 steps you get guned down.)
All in all as long as you have a decent online connection this game will provide you with countless hours of online play. And a great co-op for you and your friends to explore.
