Set up zombie spawning as in Zombie_Spawning_Setup.Ģ. There are a few key things that are required for survival mode to work: zombie spawning, a wave controller, safe zones, chopper drop point and entry/exit points, a '3d nav mesh', and (optionally) safe zone supply + heal kits.ġ.
Introduced in patch 1.03, Survival is a wave-based game mode where the survivors try to hold out against waves of the zombie horde while defending up to six separate 'safe zones'.
