We've known for a while that Sony have been tinkering with a PS Vita version of Housemarque's PS4 sensation Resogun. Now they've officially announced on PlayStation Blog that Resogun is coming to PS3 and PS Vita on December 17.
The game has been ported by Climax Studios under supervision of Sony XDev and the most notable difference between the versions is that Resogun on PS3 and PS Vita runs at 30 frames per second.
The PS3 and PS Vita versions have cross-save functionality and it should also be noted that Resogun is a cross-buy title so if you already own the game on PS4 you'll get to download the new version at no extra charge.
