About this expansion

Cthulhu Wars: Yuggoth Map Expansion is a 2015 expansion for 2–4 players, designed for games lasting around 90 minutes. It adds a distinctly unusual map featuring three new Areas with special powers and unique dangers.

The Slime Sea allows the faction controlling its overlook to summon useful Slime Mold monsters. These mid-level monsters come with a dangerous condition: they obey whoever controls the overlook. If another faction captures it, control of any summoned Slime Molds changes as well.

At the Laboratory, the controlling faction can transform Cultists into Brain Cylinders. These cylinders still produce Power like normal Cultists, but they cannot move by themselves and must be carried. They also cannot fight or be chosen to take a hit during combat.

  • Slime Sea: Summon Slime Molds, but their allegiance follows control of the overlook.
  • Laboratory: Create Brain Cylinders that produce Power but require other units to carry them.
  • Green Pyramid: Gain the benefits of the mighty Brain of Yuggoth while risking the Watcher’s awakening.

When a Brain Cylinder is “dropped,” the opposing side can capture it and gain its Power. This makes the Laboratory’s transformation powerful, but also creates a valuable objective for the other factions.

The Green Pyramid contains the mighty Brain of Yuggoth, which boosts its controller’s faction in several useful ways. However, during each Cleanup Phase, the controller must check whether the Watcher of the Green Pyramid has awakened.

The Watcher is a particularly loathsome Great Old One, later reclassified as a Terror, and is the enemy of every faction. After destroying all units at the Green Pyramid, it follows a set path around the map, wreaking destruction wherever it goes. Its own unique figure brings this roaming threat to the table.

With shifting control, unusual unit transformations, and a potentially devastating enemy, Cthulhu Wars: Yuggoth Map Expansion adds three memorable locations to the game.
