History

Zachtronics' founder Zach Barth in 2019

Zachtronics was founded by American video game designer and programmer Zach Barth in 2000. Barth started creating games early in life and further developed his programming skills atRensselaer Polytechnic Institute(RPI), where he joined the game development club.Barth studied computer systems engineering and computer science at RPI. He was one of three students leading the interdisciplinary team of the CapAbility Games Research Project, a collaboration of RPI with the Center for Disability Services inAlbany, New York.In 2008, the team producedCapable Shopper,a shopping simulation game for players with various degrees of disability.

Barth's initial games were generally freebrowser gamesoffered on his website. One of these wasInfiniminer,the block-building game which inspiredMojangto createMinecraft.His earlier, non-commercial, games included twenty that were published on his old website and "five good ones" which he transferred over to the new site. Four of these useAdobe Flashto make themcross-platform,in spite of Flash's development environment. The other one is based on.NET Frameworkfor greater programming convenience. SpaceChem also used.NET, as Barth considersC#to be his favorite programming language. For marketing reasons, Barth decided againstMicrosoft XNAwith its capability to cross-publish toXbox 360,and switched toOpenGL,which allowed him to target the three operating systems required for inclusion in theHumble Indie Bundle.

After completingThe Codex of Alchemical Engineeringand getting positive feedback from it, Barth came up with the idea of making commercial games. The first of these wasSpaceChem,which he developed the Zachtronics label for. It was also the first game where he took in a number of collaborators to help.SpaceChemwas critically praised, which led Barth to continue to develop more games under the Zachtronics label. A few ideas failed to come to light, and with expectations for the studio to make another game, he opted to makeIronclad Tactics,which was more a real-time based card game rather than a puzzle game.Ironclad Tacticsdid not do as well asSpaceChem,and Barth realized there was more a market for the puzzle games that he had previously developed, and turned back to his Flash-based games. Initially he looked to takeThe Codex of Alchemical Engineeringto make it a full commercial release, but instead ended up producingInfinifactoryand laterTIS-100.

In 2015, Barth joinedValveto work onSteamVR.He worked there for 10 months before departing.Near the time he started to work at Valve, Barth had been considering shutting down Zachtronics due to stress of running the business alongside the new responsibilities at Valve. Sometime between the release ofTIS-100andShenzhen I/O,Barth had come into contact with Alliance Media Holdings who offered to buy the studio and to manage the publishing of the games, while allowing Barth to retain his creative lead and control.Since the studio's acquisition, it has publishedShenzhen I/O,Opus Magnum,andExapunks.

In June 2019, the studio published the bookZach-Likethat includes design documents and other reference material used by Barth and his team during the development of his games.Zachtronics used Kickstarter to produce physical copies of the book by early 2019, and by June 2019 released the title as a free eBook onSteamalong with a bundle of Barth's older titles.The studio launched Zachademics in June 2019, a program to allow educational and non-profit institutions to freely download and use several of his games for educational purposes.

With the release ofLast Call BBSin July 2022, Zachtronics announced that that would likely be the last game they develop, as they "felt it was time for a change." Barth also said the decision was motivated by the fact that Zachtronics was only making games of a similar puzzle nature, keeping them "locked into doing something we didn't feel like doing forever," whereas moving on would allow him and other members of the team to work on other types of games.

Games developed

Zachtronics' games have generally been focused around engineeringpuzzle games,designing machines or the equivalent to take input and make output; these are generally part of the broader class ofprogramming games.These games, includingSpaceChem,Infinifactory,andOpus Magnum,feature multiple puzzles that are open ended in solution; as long as the player can make the required output, the game considers that puzzle solved and allows the player to access the next puzzle. Atop their solution, the player is shown statistics related to their solution which relate to some efficiency - how fast their solution completed the puzzle, how few parts they used, and the like. These stats are given with histograms from other players, including their friends via the game's storefront, that have also completed that puzzle. This gives a type of competitiveness to the game for players to find ways to optimize their solutions and improve their relative scores. Newer games also feature support for user-created puzzles.

Infiniminer

Infinimineris anopen sourcemulti-player block-basedsandboxbuilding and digging game, in which the player plays as a miner searching for minerals by carving tunnels throughprocedurally generatedmaps and building structures. According to the author Barth, it was based on the earlier gamesInfinifrag,Team Fortress,andMotherloadby XGen Studios.

Barth wroteInfiniminerin his spare time, with the help of a friend, and released it in steps of incremental updates during April–May 2009. It quickly garnered a following on message boards around the Internet.

Infiniminerwas originally intended to be played as a team-based competitive game, where the goal is to locate and excavate precious metals, and bring the findings to the surface to earn points for the player's team.However, as the game gained popularity, players gravitated towards theemergent gameplayfunctionality of building in-world objects, instead of the stated design goal of competition.

Zachtronics discontinued development of the game less than a month after its first release as the result of itssource code leak.As Barth had notobfuscatedthe C#.NET source code of the game, it wasdecompiledand extracted from thebinaries.Hackers modified the code to make mods, but also started making clients that would target vulnerabilities in the game as well as build incompatiblegame forksthat fragmented its user base. Barth, who was making the game for free, then lost interest and dropped the project, as development of the game had become too difficult.Thesource codeofInfinimineris now available under theMIT License.Building Infiniminer requires Visual Studio 2008 and XNA Game Studio 3.0.

Infiniminer is the game that initially inspiredMinecraft(and subsequentlyFortressCraft,CraftWorldandAce of Spades). The visuals and mechanics of procedural generation and terrain deformation ofMinecraftwere drawn fromInfiniminer.According toMinecraftdeveloperMarkus Persson,after he discoveredInfiniminer,he "decided it was the game he wanted to do".

SpaceChem

InSpaceChem,the player creates chemical pathways similar in style tovisual programming.It is one of three games on the recommendation page ofTeam FortresscreatorRobin Walker(the others beingHotline MiamiandFTL: Faster Than Light), with him declaring it as "Pretty much the greatest game ever made".

In March 2011, Barth stated the possibility of making expansion packs toSpaceChemand adding a free update and editor which would allow users to create their own levels which could then be shared to other users, with the best ones being picked out by Zachtronics to be published and these were released on April 29 as theShareholders' Update.Barth hinted at the prospect of a sequel and also stated that it would be fantastic to haveSpaceChemon a futureHumble Bundle.The game was included in theHumble Frozen Synapse Bundlecharitable sale in early October 2011.The following yearSpaceChemwas the featured game on IndieGameStand, a site which features indie games with a pay-what-you-want model with a portion of the proceeds going to charity. Barth chose theAgainst Malaria Foundationas the charity to which 10% of the proceeds were donated.
