It's a unusual way to announce a game, but Jason Hawkins, author for the official Playstation Blog, announced in the comments section, that Resogun is actually coming to PlayStation Vita.
"Keep watching this space, the VITA version is coming and is looking, sounding and most importantly, playing great!"
No further details were revealed, but Vita owners get this lovely game obviously soon, as it's already playable. It's curious though as developers Housemarque ruled out a PS Vita version around the original PS4 launch as the game required way to much computing power for its voxel-based graphics.
