Ben 10 DNA Combiner 2
Ben 10 always combined his dna with alien to become an alien hero. He can only manage to change into 10 aliens so whenever, he got a new dna, need to delete some old dna to make a new room for the latest. That is how the omnitrix works and he can't do anything about it. In this game, there are more aliens that Ben can handle, but he won't be using them to fight the evil aliens as this is just a match game. You need to find the match of an alien within the time frame. You need to complete all the dna to go to the next level. As you progress, new dnas are added.
