L4D_Defense

Overview

L4D_Defense is a five-player, two-team defense map on a 96 by 64 field, where players hold back waves of zombies. Each player picks from 18 heroes, including a Dragonian, a Skull Greymon, a mechanical dinosaur, and a necromancer. According to the quest log, defeating the gargoyles and field bosses yields nuclear materials, which can be combined into a nuke and used to wipe out the zombies. Gargoyles can appear outside the normal wave timing. Destroying their nest stops new arrivals, but destroying the last one restarts their attacks. Commands adjust the view range from 50 to 150, let a player suicide, and kill a hero when it is clicked.
