PS3 exclusive title, mass muliplayer shootem up, Spanning 3/ factions, and up to 256 players in a match. large scale war. Uses a new sever system to allow the 256 different users to play without lag. Of course depends on your connection but lag hosts on call of duty wont happen.
Each faction is balanced so no god like classes are available, each with thier own tech style.
Huge customiabilty, largescale maps. And thats pretty much all i know. Well i am a Xbox user soo thats was alot considering.
Ive had a friend in class harp on about it for ages.
