The first real high point is the multiplayer that gives full dimension to the game. You can play in your living room with two split-screen, 4 LAN network (yes, rare for a PS3) and the Net ... It Even more unusual is that you can experience the full adventure in cooperation with 4 friends (or guests!) with an adjustment of the difficulty of opponents functions of your group system!
The second strength is in the box, a small PSN code allowing you to download the 4 addons! A total of approximately 4.5 GB of bonus and new lands to explore. Zombies, big guns and new level cap are meeting!
The bad thing, be sure to open ports on your firewall or you may not be able to play together.
In conclusion if you like FPS if you like playing cooperatively, this is the game for you!
