Halfbrick Studioshave announced a new game for the PSP and PS3 mini’s, which as you’ve probably already guessed it's called Age of Zombies.

 

While looking similar to the Left 4 Dead NESmake and various other top-down shooters involving Zombies it does have a gimmick to help push this into the interesting category. You travel through time to fight zombies, so you’ll be fighting zombie dinosaurs, slashing up mummies and re-killing Romans.

 

Check out the trailer, looks like a nice bit of fun.
