The next game from Halfbrick Studios has been announced, Age of Zombies. The looks to be a twin stick shooter where you take out the zombie horde. Age of Zombies, releasing on PSP and PS3 minis for $4.99 on Febuary 25th.
Here is all the info we know about the game so far:
Welcome to Age of Zombies, where the wisecracking hero Barry Steakfries employs the use of time portals to stop the evil zombie scheme of Professor Brains. Using a huge pile of weapons and explosives, Steakfries is the real deal for blood-splattering needs.
Halfbrick’s first two games on minis were great, so I expect the same quality on this title. There should be a press release soon, so we will update this post when more info is out.
