All of them have been on Play Station and Xbox I think.
I can honestly say I would never buy it again. Actually we used to play every night, a group of about 12. Just looked, not single one on. All state they hate it. Were actually going back to Black Ops if we play. And I hate TreArch.
Lot of neat weapons, the dog is kool, but continuous spawning behind you, laying in corners with cross patterns with one side having distinct advantages is just not well planned. Some maps are so large and almost seem to change, they don't but are like a maze. Some of the graphics are good, very good, the castle is really a neat map, and it is sniper based. But playing on line you continuously hear people saying the hate the game. People that have no lives may enjoy, but ranking up is long for the 2 hour a day player.
