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 3 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.
