Gunsmith is pretty nice addition to the multiplayer. It alows you to make small adjustments to your gun. Like, you can add a red dot, side laser, taped mags, three round burst fire, and a suppressor. Thats only the tip of the iceberg. Guerilla mode is pretty fun. Only if you have a good team. Its like a survival mode. All in all, I loved the game. Multiplayer was good, campagin was great, guerilla was alright. Id say 8.7/10 And I have it for ps3 too.
Yeah, its definitely worth the money. And you can play the single play co-op with friends. But, you cant play it split screen. Kinda annoying, but thats the only problem I see with it.
