Dredd vs Zombies (Version 1.6)
Rebellion
Free
Publisher Rebellion sure seems to know how to make solid mobile games. They currently only have two games on the market but they're both extremely well polished. Dredd vs Zombies was the first of their offerings which I actually tried out. In this game you control your character through a small map as you navigate your way through corridors filled with spawning zombies. There is a ton of action and a bit of strategy and the overall experience leaves you wanting more.
