Atoll is a community-created Zombie Infection map. It is set on an isolated island with a lighthouse at the center surrounded by various buildings.

Atoll was contributed to the Steam Workshop.


  • The Docks: The main spawn area for RED. Near the end of the Docks are a small health kit and ammo box.
  • The Warehouse: Located next the the Docks. Two ramps can be used to get onto the roof; the broken window can also be used as an entry point, and underneath the generator is a large health kit.
  • The Lighthouse: Located in the center of the map, it has several paths which can lead to different escape/flank routes.
  • The Destroyed House: Near the lighthouse, a house with a destroyed roof can be seen. Players can jump to this spot by walking up a ramp on the building opposite.
  • The Gravestone: A lone gravestone with a Salty Dog placed on top where a medium ammo box spawns.
