“It is not an exaggeration to say that without alchemical engineering, civilization would not exist.”

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 city’s ancient Houses. But dangers lurk behind the family’s 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 engine— the alchemical engineer’s most advanced tool— 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 Berlo’s 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 game’s 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 city’s ancient Houses. Alchemists, who hold the power to create almost anything known to science, are highly sought— and highly dangerous.

Solitaire Minigame - Alchemical engineering takes focus and concentration. Take a break with Sigmar’s Garden, an original alchemy-based solitaire game. Every game is winnable, but not every game will be won…

Opus Magnum reviews and comments

Fantastic Game. Since there are no Limits (as is usually the case) in Terms of things, space used, Time or Money. You Can adjust the Difficulty of the Levels yourself by trying to optimize one or two of these Aspects. At the same time, however, everything is not possible, because the Components that are Available have some Additional Restrictions (Speed and Money, for example, is quite impossible to optimize at the same time). One is introduced with simple Tasks to the individual Components and later has to use them in increasingly complex processes. The Game really captivated me.

Really great puzzle/Programming game. What is going On? You have certain basic components that you have to assemble or convert using mechanical Gripping arms to create certain combinations. This sounds simple at first, but you only have the possibility to adjust the Positions and Program Processes before the Start. Once you start, you can't intervene anymore. That means you have to think beforehand. Here, logical, spatial and strategic Thinking is required, as well as Joy in Puzzles and Algorithms (here, of course, you do NOT need any IT skills!). Pro: Basically, I like The whole Game. It's nice tricky in many Places and offers great different Levels. Contra: There are too few Levels. So you've been busy with it for a few Hours, but I was pretty disappointed when it was done, as it got really tricky. It would be great here if there were just more difficult Levels. Maybe something like that will come after Updates doer a second Part? You don't know, but I'd be happy about it! Conclusion: Clear Buy recommendation! It's just a lot of fun and is a different Puzzle Game where you really have to turn on the Brain and there's not the Ability to just click around indiscriminately and make Progress as a result.

Early Access Review Opus Magnum is something totally different. So I haven't played anything like that in Style yet. Here are my Impressions of the Game. Graphic Design and Making up appeal to me a lot. The Menu and the Interface kept very simple, which tells me a lot. Reminds Me a little of the Menu of Endless Space and Co. The actual Game board is tidy and easy to understand. Introduction At the Beginning of the Game you get the Basics explained in some Tutorials using a small Story. With that Basic Knowledge, you can get clear with the Gameplay pretty quickly. I say right away, the Story in the Game doesn't tell you off the Stool. But at least the Effort was made to incorporate a Story at all. Gameplay At the Beginning, the Tasks are still easy to solve. But from Task to Task the Degree of Difficulty increases and you can sometimes despair really. Once you have finally solved the Problem, there is the Community Statistics that show you how good or bad You are with your Solution. If one is rather bad it has of course the incentive to revise its Construction again. So no Boredom comes up and you are motivated to tackle a Task even more Mals. Conclusion Who is on Puzzle games should definitely beat. The EAV is already a lot of Fun.
