The A.D.A.M.s. Powerful warriors created by the humans in an effort to minimize human losses in wars. They were capable of forming powerful weapons or impenetrable armor with their limbs and they could not truly die. The perfect soldiers. But what happens after the battle? Desiring not to let the A.D.A.M.s go to waste, Virgil, Deucalion's head, created a series of battle towers to stage gladiatorial matches. But he had an ulterior motive. He knew that mankind was on the verge of extinction. The A.D.A.M.s would be mankind's successors. He constructed the battle towers in such a way that they would allow the androids to gain self-awareness. This is the story of one such android. One who had spent his collective lifetimes climbing the Purgatory Towers. But one day, during one of his countless wanderings through the Towers, he picks up something that could change his life forever.

A crossover with what is possibly the most underrated game in the history of gaming and MLP. Seriously. Great gameplay, story and challenge. Great player reviews. Shit professional reviews. If you guys have a PSP, time and some money, I seriously recommend this game to you.
