Few details on T.U.M. are known at this point, aside from the fact it's being produced for release on the PSN on both the Vita and the PS3, and, it's being created by the developer behind the recently-released PSN title, Smash 'N' Survive.
Here's a description from developer, Version2Games:
T.U.M. is an action adventure title and is a story of “Jay”.
Jay wakes up from cryogenic sleep. He does not know who he is and where he is. As soon as he gets out, he discovers a world that is entirely made up of concrete and metal. There are no traces of life, no animals, no trees, not even weeds among the stones. The only remnants of nature are dried out plants with no leaves on them, just roots and dead vines.
He soon comes across creatures that have enslaved beings like himself. He must escape them to save his live and there’s only one way is to fight those creatures which makes him an accidental hero. That’s when he hears a voice, the voice of Gaia, the mother nature. She asks him to restore life to this once-thriving place.
The game is a mix of puzzle and combat with dark humor embedded in the dialogs, surroundings and even characters.
Well, maybe if I'm lucky, the Vita will have gotten a price drop by the time it comes out... though, considering how it's doing better than everyone expected, probably not.
