24 Caret Games is about to release their first game and Retro/Grade has a neat hook. It’s a shooter, but you play it in reverse.
As described on the PlayStation Blog, Retro/Grade handles like a music game, a fitting description since you can play it with a guitar controller. To prevent a time paradox, you have to fly the ship into the right spots to shoot and dodge red lasers closing in from behind. Did you make a mistake? Grab a power up and you can shift the flow of time forward, essentially giving players a chance to correct their mistake when time goes back in reverse.
Retro/Grade may not fit in the conventional definition of a horizontal shooter, but it’s backed by a novel idea. Sort of like Fret Nice, which blended the platform genre with Guitar Hero, Retro/Grade will be a PlayStation Network game for PS3.
