HalfBrick Studios' acclaimed twin-stick zombie shooter, Age of Zombies, will release on Vita in US today.
The game had previously hit the PlayStation Store in the form of a PS Mini for PSP, but its Vita release marks the first time the game has released natively to a platform with a physical twin analogue setup.
The Vita update of the 2010 iOS title comes with "remastered" graphics, a bonus 'Wild West' chapter, and a list of Survival Challenges.
The Vita entry also features slightly increased difficulty, a new health bar, global leaderboards and a suite of Trophies.
Developer HalfBrick Studios calls it "the definitive version" of the game.
There was no word of an EU release in the announcement.
