A popular Minecraft-like survival game on Steam has suddenly vanished after Microsoft issued a DMCA takedown notice, sparking fresh debate about where inspiration ends and copyright infringement begins. The delisted title, Allumeria, joined a crowded space of voxel-based sandbox and survival games that borrow familiar ideas like block-building, crafting, and exploration. But this time, Microsoft claims the similarities go too far.
According to a message shared by Allumeria’s developer, unomelon, Valve notified them that a representative acting on Microsoft’s behalf alleges Microsoft owns the copyrighted content associated with Minecraft and that Allumeria used Minecraft-related content, including gameplay and assets, without authorization. Valve’s standard approach in these situations is to remove the game quickly to reduce legal risk, which is why players can no longer find it listed on Steam.
The developer now faces a difficult decision. A DMCA counter-notice is an option, and it could potentially bring the game back. Under the typical process, if the developer files a proper counter-notice and Microsoft doesn’t initiate legal action within about 10 business days, the game may be relisted. Still, challenging a major corporation can be intimidating and expensive, especially for an indie creator who may not have the resources to hire an attorney.
The takedown has also drawn attention from other indie developers, with at least one creator publicly supporting Allumeria and arguing that it uses different technology and presents its own art direction. Supporters believe the game’s foundation and feel differ enough to stand apart, even if it shares surface-level elements common to the voxel genre.
So why is Microsoft focusing on Allumeria when Steam hosts many other Minecraft-inspired games? Critics of the takedown say that voxel survival games naturally share a similar look, and that blocky worlds, pixel-like textures, and familiar crafting interfaces are baked into the genre. Others argue the opposite: that Allumeria’s demo footage shows textures and a user interface that appear especially close to Minecraft, making it an easier target than other sandbox projects.
Unomelon has suggested that the game’s direction was influenced by more than one source, including Terraria-style combat and progression systems. Allumeria also reportedly allows players to customize blocks without relying on mods, which is presented as one of its distinguishing features.
There’s also speculation that automated enforcement may have played a role. Some observers wonder whether an AI-based detection system flagged Allumeria by mistake, especially if the decision to pursue a takedown wasn’t closely reviewed by humans. If that’s the case, the developer and fans may still have reason to hope for a reversal or clarification. On the other hand, Microsoft may believe it has strong evidence that specific elements cross the line from inspiration into unauthorized copying.
For now, Allumeria remains delisted while its developer weighs next steps. The outcome could matter not only to fans of the game, but also to the broader community of indie creators building voxel sandbox experiences in a market dominated by Minecraft.
