Sanctum: Cavern

After the initial onslaught on Elysion One, humanity turns to the subterranean depths for a rescue operation. Scientists discovered the alien lifeforms won’t venture far underground, but someone must keep them at bay as the mission moves deeper. This DLC adds the new "Caverns" map, letting you fight the infestation in a fresh underground arena. The Caverns map is available for both single‑player and multiplayer sessions, including co‑operative play. Build towers, lay traps, and combine shooter skills with strategic tower defense to survive the alien onslaught in this sci‑fi indie warfare experience.
