Now that iPhone gamers have been introduced to Barry Steakfries through his run'n gun, time-travelling adventures in Monster Dash, Aussie studio Halfbrick is bringing the shotgun-wielding hero's first game, Age of Zombies for PSP Minis, to the App Store.

In this twin-stick (virtual, of course) shooter, Barry fights all sorts of zombies -- cavemen, mummies, ninjas, and even T-Rexes -- in several different time periods as he tries to stop the evil Professor Brains and his plot to destroy mankind.

The iPad/iPhone edition of Age of Zombies features a story mode with five worlds (multiple levels in each), a Survival mode, global leaderboards, updated graphics, new menus, touch-specific controls, tutorials, and more. The iOS port will release some time next month.
