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.
