Sub Terra: Expansion -

Incubation

Sub Terra Incubation is the fourth modular expansion for Sub Terra, introducing a new character, the Scavenger, as well as a brand new horrible thing to deal with, horror spawn. Faster but weaker than their fully grown cousins, these disgusting little blighters hatch from sticky, amniotic eggs that grow in the corners of the eery caves in Sub Terra.

Interact with them at your peril...

New tiles, new horrors, a new character. Incubation adds another chapter to your Sub Terra adventures!

Investigation

Not all of you made it out alive. With the help of a mysterious corporation, return to the cave and search for your fallen friends.

Investigation adds 15 new item cards that grant your cavers powerful abilities. Recover them from the cave floor, or choose the ruthless Agent who starts fully equipped. The darkness hides many things. Be prepared.

Extraction

You've returned to the cave, and you're not alone. A new threat has emerged from the shadows - faster, deadlier, and hunting you down…

Extraction adds more horrors to the cave with the new fast-moving Leaper hazard card. Fight them off with the Mercenary, a flexible blend of cautious explorer and powerful defender. Above all else, you must carry proof of the infestation back to the surface, or die trying...

Annihilation

You're in way over your head. The nightmares in this cave must be destroyed, by any means necessary.

Annihilation introduces a totally new way to play the game.

Push deeper into the cave to reach points of structural weakness, plant powerful bombs, then get back to the exit before they detonate. The Exterminator can stop horrors from spawning and is immune to gas, helping keep your escape routes open while you complete your mission.

This isn't going to be easy....
