Left 4 Dead left a void that no other co-op zombie game was able to fill - until World War Z.
The game does an outstanding job conveying the feel of a world that has been completely overrun by zombies. Just like in the movie you have _huge_ hordes pouring in from all directions while you are constantly on the run or with your back against a wall.
The game's engine is able to render an impressive number of enemies while still performing exceptionally well even on mid tier hardware and delivering very pretty visuals at the same time.
The campaigns offer many hours of content with 5 difficulty levels and weapon and character class unlocks are plentiful.

Zombie and co-op shooter fans: Check this game out!
