Left 4 Dead is my all time favorite zombie survival game. The simple mechanics of the gameplay and the increasing ramp of difficulty is well balanced in my personal opinion. It's great for a 20 minute gaming session on Normal, and up to two hours on Expert.

But my favorite way to play is on the original campaign, but in Left 4 Dead 2. More monsters, more weapons and, best of all, harder zombies.
