I play games on my PSP sometimes. My list of the top games includes: Metal Gear Solid: Peacewalker Harvest Moon: Hero of Leaf Valley Kingdom Hearts: Birth by Sleep Assassins Creed: Bloodlines. and finally, this.
I have played 20+ games and this was one of my top 5. Believe me it won't disappoint you.
I just wonder how they get the idea to create different kinds of zombies, put'em together in a story line, and launch it as game!!! In this game, you will just see different designs, shapes and voices of zombies with different capacities of power. After some time will get bored of this.
