This is a map made for the zombie survival gamemode.
It includes three sigil rooms: hospital, electrical and combine sector command.
During wave 3 a barrage of headcrab canisters rain down and break the overpass between hospital and electrical.
during wave one the citadel animates and plays an alarm sound.
These events only occur if you are playing in the zs gamemode as they use logic_waves.
