Retro/Grade, a rhythm-based shooter played in reverse, is hitting the PlayStation Network. You can use a guitar controller!
So... how does that work? Read what Retro/Grade's all about then watch the video below. It stars a chap named Rick Rocket who just saved the universe, but went and created a temporal paradox, reversing the flow of time in the process. The rest is down to you.
Matt Gilgenbach, co-founder of 24 Caret Games, the game's developer, tells us, "As you can see from our screenshots, Retro/Grade looks like a really exciting shoot ‘em up. However, it actually plays more like a rhythm game. In order to protect the health of the space/time continuum, Rick must undo his actions exactly the reverse of the way he performed them in the first place.
"That means he has to get in the appropriate space lane from which his shot was fired and press the shoot button at the appropriate time. As well, he must avoid blocking the path of the enemy shots as they return to the enemy’s guns. If he blocks their path, it creates a paradox since he is stopping the shot before it was ever fired. All of the gameplay is timed to original retro themed tunes by Skyler McGlothlin, aka acclaimed electronica artist Nautilis."
For those without a guitar controller - or preferring a more traditional method of control - the Sixaxis is supported. There's no word on when Retro/Grade will be out yet.
