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.

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...

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!

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.

Strive with the explorers of the 'Circle' to protect & deliver the Ark. Join the mysterious travellers of the Circle and face new dangers to destroy the evil beneath the mountain. Arima's Light is the first expansion for Sub Terra II and contains 5 new explorers (the 'Circle'); a new Temple mode ('Intrepid') that contains all new hazards; and a new game mode ('Ark'), that will change the whole objective of your team's mission.

Sub Terra II: Inferno's Edge is a cooperative adventure board game. You and up to five friends must explore a tile-based volcano temple to steal a legendary artifact. To get it, you must find the path to the inner sanctum, unlock the secrets within, then escape the way you came. This is a dangerous place. You'll need to work as a team to avoid deadly traps, brave scorching lava and defeat the temple's mysterious guardians. Stick together to share your skills, or split up to cover more ground. But beware - the volcano stirs beneath you, and you're running out of time...

In Sub Terra II: Inferno's Edge, players will be progressively revealing new tiles, forming the board, mapping the volcanic temple from its sunlit entrance to its fiery core. As players explore through the temple, they will have to overcome obstacles, avoid hazardous terrain, and face the ferocious guardians of the 'artifact'. On each player's turn, after taking their actions, a random hazard will activate, making careful planning of actions essential to survival. Players must collectively locate and obtain 3 'keys', mysterious objects that are needed to gain entry to the chamber containing the legendary artifact. Your adventures must be quick, though, as the volcano stirs and as the game progresses you get closer to the volcano erupting, flipping tiles to completely inhospitable lava flows that will chase the adventurers from the cave.

In the Typhaon Wakes expansion for Sub Terra II, players are introduced to three new types of guardian to contend with in their quest to extract the mysterious artifact. Volatile guardians that can explode and cause massive damage, ranged guardians that can attack from afar, and the eternal guardian, who will not rest until you are gone from the temple.

In addition to these new guardian types and several new tile types, players will also have access to a new one vs many mode, where one player takes the role of the spirit of the mountain, Typhaon. This player will control the resolution of hazards at the end of explorer player turns using a light handbuilding mechanic. This gives that player control over the evil machinations of the mountain.
