Achtung! Cthulhu - Unexplored: Swamp + Tundra Biomes (PDF)

Sale price£6.00 GBP


Two bonus biomes for extra adventures!

It is said it is the journey rather than the destination which is important and  Achtung! Cthulhu: Unexplored helped gamemasters fill in the blank spaces which agents often simply “redline” through. 

There wasn’t quite enough space in the original print version of Achtung! Cthulhu: Unexplored to fit in everything we wanted, so this bonus PDF features two brand new biomes, Swamp and Tundra, to go deeper into the wilderness. 

Herein you’ll find a raft of new adventures as your agents attempt to navigate two perilous biomes with eight new locations, plus adventure seeds for some additional peril. 

Both Swamp and Tundra have their own unique challenges, and encounters like hazards, terrain, easter eggs and even special effects. The eight missions range from the wilds of the Scottish Highlands to the depths of a lonely arctic tower, to a camouflaged iceberg lurking in the icy seas. 

All are ready to provide an exciting climax for each journey, or simply an interesting diversion along the way.

The 55-page PDF Features:

  • Full rules for wilderness traversal, supplies, weather and survival
  • Two tough new biomes: Swamp and Tundra
  • Unique events, challenges, and encounters for each environment
  • Hazards, terrain, easter eggs and even special effects unique to each biome
  • Eight detailed mission locations and adventure seeds!
