Reverse Shooter Retro/Grade

A new shooter is coming to PSN called Retro/Grade. The game's developer 24 Caret Games is calling this the first "reverse shooter". From the trailer it looks part shooter part rhythm game. You can even play it using a guitar controller.

It looks interesting enough. I'm willing to give it a shot.
