[Free Game] Contract Killer: Zombies - awesome undead shooter
 

There's something satisfying about shooting the undead in the face. That's where Glu's newest game comes into player.

Contract Killer: Zombies game for Android (video review)

Contract Killer: Zombies lets you shoot up some zombies with a first person point of view. Great graphics and fun gameplay. It's free in the Android Market, but you can also upgrade weapons quicker with in-app purchases. I've played through about 25 stages without having to use in-app purchases, so it's possible to keep it free. Worth a look imo.
