Description

A cold new adventure awaits! Climb 10 levels of a mysterious mountain, survive freezing temperatures, uncover Agency secrets, and follow a mysterious climber's messages through a one-way walkie-talkie. Bring new technology and useful equipment back to your bunker.

Good day, Citizen!

A new adventure awaits beyond the bunker! The Mountaineer DLC introduces a brand-new mountain location with 10 levels, built around climbing, exploration, and survival in the cold.

Key Features

  • A new side story! - Follow the footsteps of an experienced climber and discover her story through voice-acted walkie-talkie messages. Mr. Prepper can listen as she reveals her story and guides him further up the mountain, while uncovering the secrets of the Agency's Cryotech experiments.

  • Use ropes, pitons, platforms, climbing chalk, an ice axe, hiking gear and more to reach new heights.

    The higher you climb, the colder it gets, so prepare with winter clothes, thermoses, heat packs. You can also take your time to rest and prepare around a bonfire before moving further up the mountain.

  • A New Enemy and New Items! - The mountain also brings a new enemy - the Puma - along with new materials, recipes, skill books and the powerful Cryotech Tesla Coil Gun.

  • Advanced Bunker Customization! - Back at the bunker, build new machines like the Elevator, Ice Cream Machine, Freeze Dryer, Automatic Storage Sorter, Titan Furnace and Cryo Sleep Pod, plus lots of new mountain-themed decorations.

  • And many more new things including achievements!

Pack your gear, prepare for the cold, and climb higher than ever before!
