Like this title suggests, I bought this game used. Which I'm glad I didn't pay full price for, because it would be a rip off.If you want a cheap game multiplayer game to waste some time between good game releases, then this is a game for you. You can play co-op with up to 4 people online as well.Levels get very repetitive. Easier setting is no fun with limited fun items. The catch is you have to play harder settings for the chance to find find items like amulets that change you into monsters. But the hard setting is no fun either, you're constantly looking for ammo and health.Another thing that sucks is you can't save when you want and can only do so at save points.Finally one thing that irked me tremendously: If you accidentally exit a game, not only do you lose your current progress, but your ENTIRE GAME PROGRESS. It happened to us, and lost everything. The game was basically reset. We just past the second level, so it could have been worse.
