Dave the Diver is heading somewhere much stranger than its usual waters for its final DLC. Mintrocket and Unknown Worlds have revealed the free Subnautica 2 Content Pack, an expansion planned for early 2027 that sends Dave and Bancho through an interdimensional portal to Proteus, the ocean moon associated with Subnautica 2.
The announced crossover promises new creatures, valuable resources, unusual recipes, new allies and clashes with enormous behemoths. Its largest stated threat is the Leviathan, described as Subnautica 2’s signature massive creature. The expansion is now available to wishlist on Steam, Epic Games, and Xbox.
It is also positioned as the final DLC expansion for Dave the Diver. That framing gives the collaboration added weight: rather than simply placing familiar cosmetics or a cameo in the game, the teams describe a portal-bound trip built around Proteus and a broader effort to bring Subnautica 2’s underwater identity into Dave and Bancho’s world.
A portal trip to Proteus
At the centre of the content pack is a change of setting. Dave and Bancho will travel interdimensionally from their own underwater setting to Proteus. The announced gameplay ingredients suggest a contained crossover adventure with its own creatures, resources, characters and food-related rewards.
That food element is particularly fitting for Dave the Diver. The expansion will let players unlock “strange and exotic” recipes, with Bancho accompanying Dave on the trip. However, the announcement does not detail the ingredients for those dishes, whether the recipes affect the core restaurant loop in a particular way, or how the resources will be gathered and used. Those are meaningful unknowns for players deciding how the crossover might fit into their existing progress.
Resources, in this context, generally means materials or valuables collected during play that are used to support progression, crafting, upgrades, quests, or other systems. The reveal confirms that Proteus includes valuable resources, but it does not specify which of those purposes will apply here. Likewise, new allies have been confirmed without details on their identities or roles.
What is clear is that the package is meant to be more substantial than a one-note reference. The stated plan is to integrate Subnautica 2 elements into Dave the Diver through a fully immersive crossover, using the voyage to Proteus as the narrative and mechanical bridge.
The Leviathan is the major danger named so far
The reveal singles out periodic confrontations with a massive Leviathan. In the announced setup, it is not merely a background creature: it is presented as a recurring obstacle Dave and Bancho will have to face during their Proteus adventure.
Periodic confrontations means players should expect the creature to return at intervals rather than necessarily appearing in only one isolated sequence. Still, the available information stops well short of explaining how those encounters work. There is no confirmed information on combat mechanics, survival systems, escape sequences, damage models, encounter frequency, or whether the Leviathan can be defeated. Calling it a boss fight, therefore, would go beyond what has been announced.
The distinction matters because the two series approach underwater adventure from different angles. The collaboration’s premise is not that Dave the Diver is becoming Subnautica 2 wholesale. Instead, it is meant to introduce a new approach to underwater exploration into Dave’s existing framework. A towering creature encounter, unfamiliar resources, and a new world to explore all create room for a different mood while keeping Dave and Bancho at the centre.
“Both games are set underwater, but Subnautica has such a distinct approach to underwater exploration,” Mintrocket Studio Director Jaeho Hwang said, describing the collaboration as an opportunity to bring “a new wave” to the Dave the Diver experience.
Why this crossover makes sense
Both games share an underwater setting, which gives the crossover a direct thematic connection without needing an elaborate justification for why oceanic exploration is involved. But their identities are still distinct enough for the premise to offer more than a simple visual swap. The developers have emphasized that difference as a creative reason for the project: the goal is to bring an unfamiliar style of underwater exploration to Dave the Diver.
That is a more useful way to read “crossover” than assuming every system from one game will transfer to the other. Crossovers can range from small cosmetic tributes to full additional campaigns. The information available here supports something in between or potentially broader: it includes a new destination, travel premise, resources, recipes, allies, creatures and a named recurring monster, but it does not yet establish campaign length, the scale of the map, progression requirements, or a list of added mechanics.
Players should also avoid treating the phrase “final DLC” as a guarantee that every lingering idea, character or feature from Dave the Diver will be revisited. It confirms the Subnautica 2 Content Pack is intended as the game’s last DLC expansion; it does not provide a roadmap beyond that point. The meaningful promise is a final fresh adventure involving Dave, Bancho, returning friends and new faces.
Unknown Worlds Creative Director Anthony Gallegos characterized the project as a “love letter” to both Dave the Diver and the Subnautica universe. That language explains the basic design challenge: it needs to feel recognizably connected to both properties, not simply borrow names and imagery from one for the other.
What has been confirmed, and what remains unknown
The reveal gives players a solid outline, but not every practical detail. Separating confirmed information from open questions is especially important with an early-2027 window rather than a precise launch date.

For PC players keeping an eye on 2027 releases, the crossover now sits alongside other projects already on the horizon, including Little Prince Tyger’s planned PC arrival in 2027. Dave the Diver’s expansion differs in one important respect: it is confirmed as free rather than a separately priced product.
What players can do now
With no specific day announced, wishlisting is the clearest immediate option on Steam, Epic Games, and Xbox. A wishlist does not unlock the expansion or confirm preloading, but it gives players a straightforward way to track its eventual release through their chosen storefront.
An announcement trailer and a press kit have also been released. Those materials may provide a visual sense of Proteus and the crossover’s tone, but the core confirmed details remain the early-2027 target, the free release, the interdimensional trip featuring Dave and Bancho, the new wildlife and resources, new recipes and allies, and the looming Leviathan encounters.
For now, the final DLC’s appeal lies in that deliberate collision of styles. Dave and Bancho are not just getting a themed outfit or a passing visitor from another game; they are crossing into another ocean world, where the ingredients for a new dish may be just as important as avoiding something enormous in the water.
