Ben 10: Ultimate Alien Warrior
Ben has been traveling the cosmos ever since he become a teenager, but that is not the point as not everyone could go there. He can do that since he is the older of one of the most powerful device in the known galaxy. He got it when he was a kid traveling with his grandpa. Ever since, he got it , trouble seems to follow him anywhere, but that is not the point here. Anyway, aliens would always put us in danger and having one of the most powerful device in the known galaxy makes you something that most aliens won't want to deal with. As Ben was investigating an anomaly, he found out that there are aliens at work and all of them are hostile. You need to beat the hell out of the aliens in this game and you can use three alien transformation to do that. You can either transform into Waybig, Chilled, or Heatblast. Each one is different from the other and you should use it to your advantage. The idea is to beat the alien one after another. After you beat the whole race then a new race would appear and you need to do it all over again.
