One of the best puzzle games ever is getting surprise DLC even though its developer kind of closed a while ago

Opus Magnum, a stellar 2017 puzzle game about building alchemical devices, is getting a surprise new DLC campaign.

Opus Magnum: De Re Metallica will release on March 17, and adds three prequel chapters to the game with a total of 17 new puzzles, new cutscenes and music, and new glyphs (machine components). It's "around half the length" of the original campaign, according to developer Zachtronics.

It's a little weird to be citing Zachtronics, never mind talking about a new DLC release from the studio...
