Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

What the developers have to say:

Why Early Access?

“We want to involve players early so we can test the core gameplay and improve it together with the community. The game is built around exploration, teamwork and survival, and feedback from real players will help us balance the difficulty, add new features and make the experience more fun.”

Approximately how long will this game be in Early Access?

“We expect the game to remain in Early Access for roughly 12 to 18 months, depending on community feedback and development progress. We will leave Early Access once we feel the game is ready for a full release.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to include more content such as additional bunker types, more monsters, new items and equipment, and improved balance. We also plan to polish performance and visuals. Currently, the game does not yet have a final ending, but we plan to expand the story and eventually include a complete ending with multiple possible outcomes, depending on how development progresses and community feedback.”

What is the current state of the Early Access version?

“The Early Access version already includes online co-op, randomly generated maps and bunkers, core survival mechanics with limited resources, and several types of enemies. It is fully playable, but there is no final ending yet and some systems are still being expanded.”

Will the game be priced differently during and after Early Access?

“Yes, we plan to increase the price after Early Access once the game includes more content and features.”

How are you planning on involving the Community in your development process?

“We want to work closely with players. Feedback can be shared through the Steam forums and our community channels. We will listen to suggestions, bug reports, and gameplay ideas, and use them to guide updates. Players who join Early Access help shape the final game.”

About This Game

Deep in the arctic wilderness, a massive crater has appeared. Beneath the snow lie mysterious bunkers with no known origin. Nobody knows who built them or why they exist.

You are part of a government task force sent into the crater. Alone or with up to three teammates, your mission is to explore the bunkers, recover artifacts and information, and bring them back to base. Time is limited. If another nation uncovers the truth first, everything could be lost.

Features

Solo or Co-op Play
Experience the mission alone or with up to four players in online or local co-op.

Randomly Generated Maps and Bunkers
Each expedition offers new layouts, secrets, and dangers. No two runs are the same.

Survival Horror Atmosphere
Limited supplies, freezing temperatures, and unknown threats create constant tension.

Gear and Equipment
Use flashlights, radios, and other essential tools to survive.

Unimaginable Creatures
Encounter lifeforms beyond comprehension. Some hide in silence. Others swarm without warning.

Mature Content Description

The developers describe the content like this:

This game contains stylized scenes of violence and psychological horror. While the visuals use a retro-inspired art style and are not realistic, players may still encounter unsettling imagery and stressful situations.
