Retro/Grade, the, uh, backwards shoot-em-up that you control with a guitar, finally makes its way to PlayStation Network on PS3 August 21. It'll be sold both by itself and as a bundle with its soundtrack. Developer 24 Caret Games posted the above new trailer to mark the occasion.

We're happy to report that if you've recently purged your home of plastic guitars, you can use a regular controller as well - but that removes one of the many levels of incredible weirdness.
