About Opus Magnum
โIt is not an exaggeration to say that without alchemical engineering, civilization would not exist.โ
Hailed as the most promising alchemist of his generation, Anataeus Vaya has just accepted a position as Head Alchemist of House Van Tassen, the oldest and richest of the cityโs ancient Houses. But dangers lurk behind the familyโs opulent facade, and alchemy alone may not solve every problem.
Opus Magnum is the latest open-ended puzzle game from Zachtronics, the creators of SpaceChem, Infinifactory, TIS-100, and SHENZHEN I/O. Master the intricate, physical machinery of the transmutation engineโ the alchemical engineerโs most advanced toolโ and use it to create vital remedies, precious gemstones, deadly weapons, and more.
Design Machines - Design and build machines that carry out alchemical processes using a variety of components including programmable arms, customizable tracks, and more esoteric devices like Van Berloโs wheel and the Glyph of Animismus.
Open-Ended Puzzles - Compete against your friends and the world to build the simplest, fastest, and most compact solutions to the gameโs challenges. Export animated GIFs of your elegant designs to show them off.
Steam Workshop - Make and share your own puzzles with full Steam Workshop integration and an easy-to-use puzzle editor. Play the top user-submitted puzzles in the prestigious Journal of Alchemical Engineering, curated by Zachtronics!
Rich Story - Intrigues and dark plots swirl around the cityโs ancient Houses. Alchemists, who hold the power to create almost anything known to science, are highly soughtโ and highly dangerous.
Solitaire Minigame - Alchemical engineering takes focus and concentration. Take a break with Sigmarโs Garden, an original alchemy-based solitaire game. Every game is winnable, but not every game will be wonโฆ
