Issues Slowing Down Subnautica 2’s Release

1. Early Access Delayed to 2026

• Subnautica 2 pushed back to 2026Originally set for an Early Access release in 2025, Subnautica 2 has now been delayed until another year. Unknown Worlds mentioned wanting time to perfect biomes, introduce more creatures and deepen narrative before launch.
• Krafton is in favor of the delay, stating that it was taken to ensure a high quality game and to protect Subnautica as a franchise from a premature incomplete launch.

2. Legal Dispute and Leadership Shakeup

• Massive lawsuit: Former leadership of Unknown Worlds (Cleveland, Gill and McGuire) is suing Krafton for releasing delays aimed at avoiding a $250M earnout bonus (established if Early Access had launched in 2025).
• Krafton dismissed the trio, claiming that they had abandoned their work on development and downloaded sensitive data prior to leaving.
• Outgoing leadership insists no, the game was good to go and they just needed time to spread out costs.

3. Community Backlash & Reputation Risk

• The news of the delay and leadership firings prompted fan unrest — including calls for boycotts and concerns about game integrity.
• The team was also quick to establish that Subnautica 2 is not a games-as-a-service (GaaS) game. No season passes, no loot boxes, no subscriptions — pledge reiterated after backlash.

4. Milestone Review & Scope Reduction

• Leaked internal documents showed Krafton’s fears that Early Access wouldn’t ‘drive IP growth’, due to the game not having biomes, creatures or narrative content. They advised a 30% scope boost before ship.
• These internal reviews around milestones have now been confirmed authentic by Krafton themselves, with the delay being framed as quality first.

Story & Setting

• You are an arriving researcher that is sent to figure out the reality of the Precursors (the old aliens).
