PlayStation Blog mentions that PixelJunk Monsters: Ultimate HD will include the original game, plus Encore expansion, along with extra towers, enemies and levels from the PSP's Deluxe edition. The game is being ported by Double Eleven, which previously handled ports for LittleBigPlanet and Limbo.
"Monsters Ultimate HD has more than 30 hours of gameplay set across story and challenge levels. All of the graphics have been remastered for the PS Vita's high-resolution screen, and we added touchscreen input to provide more control of Tikiman," wrote Double Eleven COO Mark South on the PS Blog.
Eurogamer mentions the game will launch in "late summer," with PC and Mac versions requiring your protection from the swarms soon after.
