Mycelarium Release Date: Planned Nov 3, 2026 (Steam)
Mycelarium's planned Steam release is Nov 3, 2026. Dev news says hopefully that date; price and unlock time are not listed yet, and we mark what is confirmed.
Fact labels: Verified Observed in Demo Inferred Not announced What these mean
Mycelarium, the Steam game by PLAN KAPKAN, is listed for a planned full release on November 3, 2026, while a free demo is already playable on Windows. This page tracks what Steam and the developer have said as of October 31, 2026, three days before that date.
When is the Mycelarium release date?
The Mycelarium Steam store page shows Planned Release Date: November 3, 2026. Verified That field is the primary store-side date players see before launch.
PLAN KAPKAN is also the developer and publisher, and the listing is Windows only with English interface and subtitles. Verified For hardware expectations, see our system requirements page.
What has the developer actually said?
On October 30, 2026, PLAN KAPKAN posted DEMO 2.0 is OUT! on Steam news for Mycelarium. The post ends with: Full release is very very soon! (hopefully November 3rd). Verified
That wording aligns with the store’s planned date but uses hopefully, so wiki pages should describe the launch as planned, not as a fixed guarantee. We do not know whether the date could slip; we only report what is public.
Mycelarium official Demo trailer
Can you play Mycelarium before Nov 3?
Yes. The Mycelarium demo is a separate free Steam app (AppID 5371480) that went live on October 8, 2026. Verified Demo 2.0 shipped on October 30, 2026, adding a save system, Repeller mushrooms, new visuals, and balance tweaks. Verified
Our Mycelarium demo guide explains what the slice includes and how it differs from the full-game pitch. If you want to see upgrades and mushrooms in action before launch, the upgrade tree overview summarizes what official screenshots show.
What is still not announced?
Several launch details remain unknown on official channels as of October 31, 2026:
- Price — Steam’s price overview was empty; no USD or regional price was shown. Verified
- Unlock time — No hour, time zone, or global roll-out schedule was published. Not announced
- Mac, Linux, and consoles — Store platforms list Windows only; other platforms are not announced. Verified
- Steam Deck status — No official Deck compatibility rating was found; we do not cite third-party guesses. Not announced
Early access, betas beyond the public demo, and any promo codes are likewise not announced. Our Mycelarium FAQ collects other common pre-launch questions (codes, saves, multiplayer).
How will this page change on release day?
After November 3, 2026 (or whenever the full game actually appears on Steam), we plan to re-check the store page for release status, price, and any new developer news, then update this article’s lastModified date and sections above. That is an editorial plan, not a promise from PLAN KAPKAN.
If the store date changes, we will replace the planned date here and note what changed. Until then, treat November 3, 2026 as Steam’s planned date and the developer’s hopefully wording as the same target with less certainty.
