Just a heads up - but if you head to your favorite version of the PlayStation Store, that is either via the PS3 or PSP, you can find a brand new demo for Patapon 2!
The demo features a sample of it's multiplayer co-op mode, which can be played via AD-HOC wireless. In it players work together as different Patapons to move an egg through a level using various beat based attacks and moves.
If you download it and check it out, let us know how it is!
