Here is a review on the one game that teaches you how to survive a zombie apocalypse.
Pros
+ Can be played again after beating it, and it still keeps it's charm
+ The multiplayer is amazing
+ The cooperative play is also sufficient if you want to enjoy the game
+ The graphics were rendered very nicely, but it still has a nice looking cartoony taste.
Cons
- Small choice of characters for single-player
- The multiplayer is crowded with little monst...I mean wonderful wonderful children
Summary
In all this game was worth the wait and is worth the money. Hearing little kids scream may get old, but it ends. This game is something that will always be a very big example to the new zombie survival genre of games.
