The HD remake of Dreamcast favorite Jet Set Radio will be coming out on iOS and Android this summer, alongside the previously announced XBLA, PSN, PC, and Vita editions.
The mobile versions of the game will allow players to use photos as graffiti tags, and share achievements on social media with OpenFeint. Most importantly, the extremely bright-looking game will feature retina display support.
Personally, I think the game is already tough to handle with a controller, so using a touchscreen sounds really tricky. Then again, it might be exactly what the game needs.
