Stop me if you've heard this one before: Zombies now roam the Earth; survivors need to be found and rescued; and you're their last hope with a handful of weapons and a handy-dandy UFO to escape their clutches.

Killing Zone by CB Project is a survival action title that pits you against several different scenario types, often requiring mass extermination of the zombie hordes out to kill you. As you earn cash you'll be able to unlock new weapons and upgrades along with a mech that you can pilot to dispense mayhem and destruction against these shambling foes. Movement around the screen is handled by a basic virtual stick, though shooting is limited to two directions which helps to simplify the action as you attempt to use weapons like a laser or a flamethrower to cause damage to multiple opponents.

Unfortunately the game can get repetitive quite early on thanks to poorly balanced scoring system that provides a few opportunities to 'max out' or at least trivialize the challenge early on. Once the dangling carrot of upgrades is no longer a concern, all you're left with is a fairly repetitive handful of modes to play through. The game itself also feature wonderfully amusing and detailed pixel-art, but the interface and English translations don't feature the same dedication, with the 'tutorial' merely pointing out interface features instead of the gameplay itself.

Killing Zone is an amusing action title, but a short lived experience once you unlock some of the game's more powerful weapons. If you're after something lighthearted and a bit mindless you can't go wrong here, but playing on Normal instead of Easy is recommended.
