Indie game developer and publisher Zachtronics has announced the latest DLC coming to Opus Magnum, as they showed off the De Re Metallica content. This is basically an all-around boost in content to the game, if you're willing to drop a little extra cast for it, with enough content to equal half the size of the title. We have the dev notes and the trailer here as the content arrives on March 17, 2026.

De Re Metallica DLC
De Re Metallica is about half the size of the original game, featuring 17 new puzzles across three chapters, with three new glyphs, as well as a new take on Solitaire. In a prequel story set before the events of Opus Magnum, De Re Metallica, follows a maverick alchemical researcher named Saverio Daas, who believes he can unlock metallurgical secrets that even the Imperial Academy has not uncovered! Along the way he'll clash with established orthodoxy, bicker with his assistant, and attract attention from the Great Houses. What happens when a new invention becomes worth much more than its weight in gold?
