Allumeria and the Microsoft DMCA, Explained

What actually happened

10 February 2026. Unomelon, the solo developer behind Allumeria, posted publicly that Microsoft had filed what the developer described as a false DMCA claim against the game on Steam. Part of the claim was shared on the Allumeria Discord: Microsoft alleged that Allumeria used Minecraft content “including but not limited to gameplay and assets” without authorisation. The Steam page — at that point the demo, since the game had not yet released — was taken down.

11 February 2026. Microsoft withdrew the claim. The developer shared the email correspondence confirming it, called it the best-case outcome, and noted that the Steam page and game were fully restored and that no counterclaim was needed, which also meant no route to a lawsuit.

Another post on the Discord suggested the claim may have been automated rather than the result of a human review, which is the detail most of the coverage focused on. Reporting at the time (GamesIndustry.biz, PC Gamer) noted Microsoft had been contacted for clarification.

Why people are still searching for it

Three reasons, and they show up as distinct searches:

• “was allumeria delayed because of mojang” — it was not. The takedown lasted roughly a day in February; Early Access shipped on 28 August 2026 as announced two weeks earlier, on schedule.
• “allumeria kicked off steam” / “taken down” — briefly true in February 2026, not true now. The game and its demo are both on Steam.
• “allumeria lawsuit” — there was no lawsuit. The claim was withdrawn before a counterclaim was filed, which is specifically what prevented one.

Is the game safe to buy?

That is the practical question behind the search, and the answer is yes: Allumeria has been on sale since 28 August 2026, is patched several times a week, and the DMCA claim was withdrawn six months before launch. Steam purchases are also not conditional on a page staying up — a delisted game stays in your library.

What the episode changed

Nothing mechanical in the game. What it did do is make the developer’s position on the comparison explicit. Allumeria is a voxel sandbox written in C# with OpenTK, OpenGL and SoLoud — its own engine, not a Minecraft mod and not a fork — and its progression structure (biome bosses gating tiers, keys, dungeons) comes from a different tradition than Minecraft’s. Our Allumeria vs Minecraft and Hytale comparison covers where the genuine similarities and differences are.

The developer’s own closing comment on the affair was a hope that automated claims like it get investigated or prevented, because DMCA claims can do serious damage to independent creators.
