A simple yet effective map for obtaining the Zombie Genocidest (53,595 kills) achievement in Left 4 Dead. To prevent crashes on lower-end hardware, the kill-rate has been lowered to a reasonable 72,000 per hour, which is still enough to go from 0 to 53,595 in about 45 minutes.
This DOES require the L4D2onL4D Addon Support.
The Survivors find themselves in a strange world, and must find a way to get out of the danger zone.
A L4D2 entry to the Orange Map phenomenon ported to L4D1. Featuring wide-open terrain, plenty of unique quirks, and a visit from some special guests. Ideal for casual play.
-This campaign requires shaders to be set to medium or higher.
A simple map created for the sole purpose of killing, killng, and more killing. Don't take this map seriously. The arena houses enough supplies to last for years. The map is a great way to rid yourself of stress, or to rack up kills on certain weapons and gather Achievements wherever applicable.
Don't bother asking this to be ported to Left 4 Dead 2. The answer will always be no.
