Free. Oh my God, it is good if you like zomb games. You can places people & shoot if you turn the phone around. Theres a shop to get stuff like in game stuff, wallpapers etc. too, with cash you earn in the game for killing zombies.
Rocket Raid Free - ok, so it's my game but I think you'd enjoy it.
It is based on the arcade game scramble and getting some good ratings on market place.
