Delverium Early Access: What's New Compared With the Demo

Is Delverium Out Now?

Yes. Delverium is now available in Steam Early Access. The global release went live on September 21, 2026 (PDT) — September 22 in some other time zones, which is why you will see both dates quoted. They describe the same launch.

Early Access is the full game in active development rather than a separate limited build. Systems work, content is playable, and balance is still moving: recipes, progression and other mechanics may change during future updates.

What Early Access Adds

These are the confirmed additions over the demo, and all of them are in the build you can play now:

• A wider variety of biomes
• Additional bosses
• Additional enemies
• Additional materials
• Additional equipment
• More building options
• More farming options
• More crafting options
• Fishing
• Cosmetic equipment
• Lore
• Split-screen and online co-op
• Full controller support
• Multiple interface languages
• Steam achievements
• Many hours of playable content

We have deliberately left counts and specifics out of that list. How many biomes, which bosses, what each new crafting option costs — those are exactly the details that shift during Early Access, so they are not worth publishing until they settle.

"Many hours of playable content" is the developer's own phrasing rather than a number we measured. We are not putting an hour figure on it, because any figure would be a guess about how you personally play.

Fishing is new enough that it has its own guide, which covers the confirmed loop, where bait comes from, and whether rod and bait quality matter.

Early Access vs Demo

The demo was a limited slice of the game. Early Access is the full game, still being developed — which is why the developer describes it as Early Access rather than as a finished release.

Practically, three things change if you are coming from the demo:

• There is far more content. The list above is what was added on top of the slice you played.
• Your character can come across, your world cannot. The next section covers that.
• Early Access is the paid release. The demo was the free try-before-you-buy version; the Early Access build is the game itself.

This also means demo-era advice does not automatically still apply. Early Access changed a great deal, so a guide written against the demo may describe systems that have moved.

Fishing and Critters

Fishing is one of the additions in Early Access, and it is a complete loop rather than a single item: craft a fishing rod, collect bait, and cast into a nearby body of water. The quality of the rod and the bait can affect the type of catch.

The bait source is one of the more useful things to know early: catchable critters can be used as fishing bait. That means the creatures you pick up while out gathering double as fishing supplies, so you do not need a separate bait run.

Fish then feed the same cooking and food system your farm does, which is the practical reason fishing sits alongside farming rather than replacing it. The fishing guide covers the loop in more detail.

What we are not listing: fish names, bait names, rod recipes, fishing spots, biome-specific or rare fish. None of that is verified for the current build, and a wrong fish list is worse than no list.

Cosmetic Equipment

Source: June 7 development update (Cosmetics).

Early Access adds cosmetic equipment, and this is one of the clearer systems in the release because official development information spells out how the slots behave:

• Cosmetic armour slots exist as slots of their own.
• Items equipped in a cosmetic slot are for visual appearance only — they provide no stat bonuses.
• A cosmetic item overrides the visual appearance of whatever is equipped in the matching normal equipment slot.
• One confirmed example is a hair clip item, which can hide or override helmet visuals.

That is the whole of what we are stating. We are not listing cosmetic items, how they are obtained, or what they cost, and we are not describing a wider transmog or wardrobe system — none of that has been confirmed.

The practical point is simply that wearing a cosmetic piece does not cost you stats. If you want the look without the trade-off, that is what the slots are for.

Multiplayer Improvements

Early Access includes both split-screen and online co-op, and the two player limits are different numbers:

• Online co-op: up to 8 players.
• Local split-screen: up to 4 players.
• Split-screen and online players can play together.
• Full controller support is available.

Steam Remote Play Together and Steam Cloud are both listed for the game, and Delverium is Steam Deck Verified. The multiplayer guide covers what each of those means, and where the confirmed detail stops.

If you are setting up a group, the beginner guide applies to the whole session rather than to one player — the early priorities are the same for everyone.

Demo Save Compatibility

If you played the demo, your character can be imported into Early Access. Your world cannot — demo world saves are not compatible with the Early Access version.

The import option is shown before you start the game for the first time, and it needs the demo plus your valid demo character saves on the same PC. We have not confirmed how to reopen the import prompt if you skipped it.

The developer recommends starting a new character for the best Early Access experience, given how much more content there is. The demo save transfer guide covers all of it, including what to do if you skipped the import screen.

What Is Available Now?

Available now

Everything in this list is in the build you can install today:

• Single-player
• Online co-op for up to 8 players
• Local split-screen co-op for up to 4 players
• Split-screen and online players in the same session
• Building, crafting, farming and fishing
• NPC recruitment and settlement building
• Cosmetic equipment and Steam achievements
• Additional lore, materials and equipment
• Full controller support and Steam Deck Verified
• Multiple interface languages

Multiplayer has its own guide, which keeps the 8-player online limit and the 4-player split-screen limit apart. If you are checking whether your PC can run any of it, the system requirements page has the official figures.

What Is Planned Next?

Planned for shortly after launch

The developer's immediate post-release plans are:

• Initial balancing and fixes
• Quality-of-life improvements
• New effects and visual updates
• More enemies
• More loot

Longer-term plans

Further out, the developer has listed:

• Official modding support
• Expanded NPC behaviours
• NPC quests
• More NPC options
• Additional biomes
• Additional bosses
• Deeper lore
• More gameplay features
• Pets
• Mounts

Possible later additions

The developer has also raised two items as possibilities rather than commitments:

• More Steam achievements
• Expanded language support

More biomes and more bosses appear twice on this page on purpose: Early Access already adds some over the demo, and the roadmap promises more again on top of that. Both statements are true at once.

No dates are attached to any of it. The developer has not given a timeline beyond the Early Access duration estimate below, so we are not going to invent one.

How Long Will Early Access Last?

The developer currently expects Early Access may last up to approximately two years, depending on player feedback.

Treat that as an estimate rather than a date. It is a rough figure the developer has given for how long the game may stay in Early Access, not a commitment to a 1.0 release on a particular day, and it explicitly depends on how feedback goes.

What it does tell you is the shape of things: expect the game to keep changing for a long time, and expect guides written against any single build to go stale. Delverium pages on this site carry the build they were checked against rather than an assumed current state.
