Located east of Stormgap Coast, the Forbidden Isle is a hostile and miserable place. Inhabited by legions of Iron Spiders, likely originating from the Spider Factory situated in the middle of the isle and aggressive Tech Hunters who wish to lay claim to the lost secrets, this small land mass should be explored by either the mad or the courageous. Aside from the hostile enemies, there is often a blanket of acid rain that covers the island making exploration even more perilous without the proper protective gear.


There are no Major Towns or Minor Outposts in the Forbidden Isle. This zone does not spawn Nests or Camps.

Ancient Locations[]

These are places which do not have competent inhabitants. Ancient Locations are usually lost outposts or ruins. Beware: sometimes these locations contain territorial protectors such as Security Spiders.

Homeless Spawns[]

These are squads which spawn without being tied to a location, camp, or nest. This list is in order of likelihood.

These squads can potentially spawn in this zone if certain World States have been reached.
