Early Access roadmap
Developer Unknown Worlds follows the original game's Early Access strategy: get the foundation right, then expand dramatically. The official roadmap (subject to change):
- Update 1 — Quality of Life: biomod / blight / wreck / vehicle-docking improvements, extra passive biomod slots, expanded storage, a sprint mechanic.
- Update 2 — Co-op Centric: HUD signal & base-building improvements, in-game voice chat, player emotes, trading, and the ability to revive a downed co-op partner, expanded character customisation, refined pinned recipes.
- Larger expansions: new world regions / biomes, more creatures, new resources, new tools, another vehicle, and the next chapter of the story.
- Ongoing hotfixes, balance and optimisation throughout Early Access.
Named planned regions: the World Tree (the inaccessible endgame region, source of the Proteavirus) and Xanadu (revealed via an Alien Ruins hologram), possibly a Zezura Desert. The final map is confirmed larger than both prior titles.
Krafton acquisition & lawsuit
Krafton acquired Unknown Worlds in 2021 for $500M in equity plus an up-to-$250M performance earn-out. In July 2025, Krafton fired CEO Ted Gill and cofounders Charlie Cleveland and Max McGuire, initially citing launch-readiness concerns, later alleging unauthorised projects.
Litigation revealed that Krafton's CEO — alarmed by projected $191–242M payouts and fearing he would be seen as a "pushover" — orchestrated a month-long plan to manufacture termination justifications, including consulting ChatGPT for messaging strategy (first denied, then admitted under oath). On March 16, 2026, Delaware Chancery Court Judge Lori Will ruled the firings breached contract, ordered Gill reinstated with control of the Early Access launch, and extended the earn-out deadline ~9 months to September 15, 2026. Cleveland publicly stated the game was already EA-ready, contradicting Krafton. The dispute is reported as ongoing.
Launch reception & sales
A massive commercial success: ~2 million copies sold within about 12 hours (1M in the first hour). Peak concurrent players reached ~651,000 across Steam, Epic and Xbox — roughly 9× the original Subnautica's launch peak. Community pushback focused on the EULA / terms of service criticised as "predatory" and early-build performance / optimisation caveats.
