The announcement, shared via the game's Steam page, positions the update as the last major DLC package following years of post-launch content and support from the developer.
The crossover transports protagonist Dave — accompanied by his partner Bancho — through a mysterious portal into Subnautica 2's ocean moon Proteus.
According to Mintrocket's Steam listing, the expansion introduces unfamiliar waters, new alien creatures, and valuable resources to collect and cook, extending the game's core loop of diving, gathering, and restaurant management.
In journalistic terms, Mintrocket summarizes the expansion as a plunge into an otherworldly marine environment: the studio says players can expect new waters, strange fauna, and unexpected discoveries on Proteus.
The developer adds that the Blue Hole will host an unexpected visitor from the other side, and that Dave's trip beyond the portal will yield unusual catches and ingredients that tie back into the game's culinary systems.
Key points announced on the Steam page include:
- Free expansion planned for Early 2027.
- Crossover content set on the ocean moon Proteus from Subnautica 2.
- New creatures and resources to discover, with implications for Dave's fishing and cooking gameplay.
- Narrative framing that sees Dave and Bancho step through a portal to retrieve strange catches.
Mintrocket's decision to make the crossover a complimentary update underscores the studio's sustained post-launch engagement with Dave the Diver.
The publisher's Steam listing also included multiple screenshots highlighting the new environment and creature designs, giving players an early look at what to expect when the DLC goes live.
For players who follow Nintendo coverage, Dave the Diver has been part of the broader conversation around indie successes on platforms such as Nintendo Switch and PC (Steam).
This crossover with Subnautica 2 adds a notable collaboration to Mintrocket's slate of updates and will be the final major DLC installment the studio has scheduled for the title.
More details, including exact launch timing and platform-specific rollout information, will be provided by Mintrocket as Early 2027 approaches.
Until then, fans can anticipate a free expansion that blends Dave the Diver's familiar mechanics with Subnautica 2's alien oceanic themes.
