I played this game both solo and co-op. The game is very cool at first once you start unlocking characters and new abilities. One of the best parts is the fusion ability of the game, it really stirs up some laughter as for example storm puts down a tornado and gambit throws purple cards into it and causing a cataclysm. Its fun for a while, but then it gets very VERY repetitive, even though some boss fights are fun, most of them are very easy. The story line is pretty cool actually, there's a lot of conflict but the biggest part of the game is the boring game play. If you play co-op (which you should do) the game gets 10x better and its a lot more fun. Overall this is what i thought of this game.
Gameplay- 6 very fun at first then gets boring fast Story-8 very in depth, and if your a marvel fan it's great. Sound- 7 Graphics- 5- they got very lazy on the graphics and it looks like the first one, with a few improvements, videos are great, but game play wise its pretty horrible.
Overall- 6 I would rent if you had a friend, and you guys were bored.
