Permafrost is in Steam Early Access as of October 9, 2026, with solo play and online co-op for up to four players. The developers have stated the build will be treated as unfinished for at least 12 months while biomes, quests, NPCs, and equipment are added.
Permafrost launched in Steam Early Access on October 9, 2026, from developer SpaceRocket Games and publisher Toplitz Productions. The game is set on a frozen Earth after the moon shattered, and it supports solo play and online co-op for up to four players. A rescued dog scouts, warns of danger, and carries luggage. The Early Access build arrives with its main features already in place, and the developers have stated a window of at least 12 months before the game is treated as finished, with a roadmap covering biomes, quests, NPCs, and equipment.
The run-up to launch followed a staged rollout. A playtest ran from October 2 at 21:00 JST to October 6 at 21:00 JST, with each session lasting one hour from launch and an initial small wave before more players were let in. Coverage of the playtest described online co-op for up to three friends, while the early access announcement and launch trailer both put the number at four players. The playtest story and the launch stories disagree on this point: the final release supports up to four.
Marketing centered on survival mechanics rather than combat or story. The launch trailer showed exploration of snow-covered cities, trading with NPCs, and base building with companions; players control Luke, an engineer skilled at rebuilding, and must maintain body temperature, gather resources, and repair abandoned shelters. The game includes battles against dangerous wild animals and hostile survivors, and it has no constant gunfights or fantasy elements. A separate story trailer introduced the world setting, and Japanese language support is included.
Before gamescom 2026, the team released a new key visual and reverted to the original after community feedback, in three days. A wishlist campaign tied the launch discount to wishlist counts, confirming 15% off at over 450,000 wishlists and a maximum of 30% at 1 million.
