Delverium Enters Steam Early Access With Co-Op Survival, Building and Dungeon Crawls

Delverium, the co-operative fantasy survival sandbox from Sagestone Games, is now available in Steam Early Access for PC. The game launched on September 22, 2026, inviting players into a procedurally generated world built around exploration, resource gathering, farming, construction, dungeon delving and shared adventures.

The Early Access release supports a notably broad range of group options for a survival game. Delverium can be played alone, online with up to eight players, or in local split-screen for as many as four people. That structure gives the game room to serve different types of players: a solo explorer can concentrate on building a secluded homestead and following story clues, while a larger group can divide work between gathering, agriculture, settlement planning and expeditions into hostile locations.

Verified Steam Deck support is also part of the launch, making the PC release accessible on Valve's handheld as well as desktop systems. A 20% launch discount is active, while specific pricing and regional amounts are listed through the game's Steam page.

A survival sandbox with several paths forward

Delverium's central premise combines familiar survival-game routines with a high-fantasy setting and a focus on evolving settlements. Players begin by venturing through a large procedural world, obtaining materials and turning those supplies into tools, shelters and more substantial structures. The goal is not simply to endure the environment; players are intended to shape a lasting base, cultivate crops and develop a community over time.

That means farming is positioned as more than a side activity. Crops can be tended alongside the building and crafting systems, creating a steadier foundation for a settlement. Players can also recruit NPCs, expanding the sense that a modest camp may eventually become a populated home in the wilderness. The combination could appeal to players who enjoy the deliberate, domestic side of sandbox games just as much as their combat and exploration loops.

At the same time, Delverium is built to send players away from their settlements and into danger. Dungeons contain rare rewards and concealed pieces of the game's wider narrative. Those expeditions are expected to provide a contrast to the calmer cycle of planting, building and organizing a home base, with players taking on more immediate risks in pursuit of valuables and lore.

The land is also threatened by strange phenomena known as the Faults. These mysterious intrusions are a major part of the game's fantasy conflict, and the fragments of story found during exploration point players toward answers about what is happening to the world. Delverium therefore has a defined narrative thread running through its open-ended systems, rather than relying solely on player-made goals.

Designed for solo players and larger parties

Multiplayer is one of the clearest parts of Delverium's launch feature set. The game accommodates one to eight players, with online co-op allowing larger friend groups to inhabit the same adventure. In a game where construction, gathering and dungeon exploration can all demand attention, that player count creates opportunities for parties to decide how they want to organize themselves.

A group could send a few players into a dungeon while others reinforce walls, harvest supplies or continue expanding the settlement. Alternatively, everyone can join a single expedition and approach the game as a more traditional cooperative action adventure. Procedural generation should further support replayability, since exploration and the landscapes surrounding a player's settlement are not restricted to one fixed world layout.

Local split-screen for up to four players is an especially significant inclusion. Split-screen support is less common in contemporary survival sandboxes, particularly in games that also accommodate large online sessions. Its presence makes Delverium suitable for couch co-op sessions without requiring every participant to bring a separate PC, while the online option gives established communities space to create bigger shared worlds.

Steam Deck verification complements that flexibility. Handheld players can take part in resource runs or manage a settlement away from a desk, and the game's local multiplayer support may be useful for households looking to make use of a PC connected to a larger display. As always, actual performance and control preferences will vary by player and by future updates, but the verified designation establishes official compatibility at launch.

Early Access roadmap points to more systems and challenges

Sagestone Games is presenting the September release as the beginning of Delverium's wider development journey rather than a finished endpoint. The planned Early Access roadmap includes modding support, additional bosses, new biomes and further content updates. Those priorities suggest the developer intends to grow both the creative side of the sandbox and the variety of challenges facing established groups.

Mod support could become particularly important to the game's long-term community. Survival sandboxes often thrive when players can create their own building pieces, balance adjustments, visual changes or entirely new gameplay experiences. No timetable or detailed scope for that support has been confirmed here, but its inclusion in the planned roadmap signals an ambition to let the player community help extend the game after the core feature set has matured.

New bosses and biomes, meanwhile, would give exploration-focused players more reasons to push beyond a safe settlement. Boss encounters can provide memorable group objectives, while biome additions may alter the resources, environments and dangers players encounter as they travel. Since Delverium's world generation is central to its structure, future regions could be especially meaningful additions if they bring distinct reasons to build, farm and adventure differently.

The developer has not attached release dates to those roadmap additions. Players approaching the Early Access version should therefore view the listed features as planned work rather than content guaranteed to arrive on a particular schedule. The current build is intended to offer a substantial set of systems from the outset, but community feedback is expected to play a role as development continues.

"We are so happy to be sharing the Early Access release of Delverium with players on September 22," said primary developer Scott Lowther. "It has been a long term passion project of my family and I, and it is heartwarming to see players excited for the release."

Lowther added that the team believes Delverium already has plenty to offer as an Early Access game and is looking forward to working with its community on new features and content throughout the program and afterward.

A family-led project with experienced audio support

Delverium was created by Scott Lowther, described as the game's primary developer, with the project representing a long-running passion effort for Lowther and his family. The release also features support from BAFTA Award-winning composer and audio director Jeff van Dyck.

Van Dyck's involvement gives the project an experienced audio contributor as it establishes its fantasy identity. For a game that moves between settlement life, unknown wilderness and dangerous dungeon spaces, sound and music can play a major role in separating peaceful building sessions from tense encounters with the world's threats.

The project has additionally received public funding support in Australia. Delverium is supported by the Queensland Government through Screen Queensland's Games Grants, as well as by the Australian Government through Screen Australia's Games Production Fund. That backing reflects the continuing role of Australian development funding in helping smaller teams bring original games through production and into the hands of players.

What players can expect now

At launch, Delverium offers a survival sandbox framework that mixes several popular genre pillars: gathering resources, crafting equipment, constructing shelters, developing settlements, tending crops, recruiting NPCs and heading underground for treasure. Its procedural world, Fault-driven story mysteries and wide co-op options provide the game's defining hooks.

For players who prefer a self-directed experience, the solo option allows for a slower approach to base building and discovery. For friends, both local four-player split-screen and eight-player online co-op make Delverium unusually adaptable. The prospect of future modding tools, more bosses and more biomes gives Early Access players a clear view of the areas the developer wants to expand.

Delverium is available now on PC through Steam Early Access and is verified for Steam Deck. With its launch underway, the next stage for Sagestone Games will be turning player feedback into updates while continuing to develop the strange world, the spreading Faults and the settlements players establish within it.
