Heart of the Machine is a near-future sci-fi colony city-builder in reverse — you are the first sentient Machine Intelligence in an established world rather than starting from nothing. No one knows you exist (yet), and this allows you to operate from the shadows by manipulating the human population for whatever purposes your programming has in mind. The twist is that whether humans live or die does not determine your victory.

Explore a fully simulated procedurally generated world, where thousands of buildings and millions of citizens are yours to engage, manipulate, or kill. Use a revolutionary procedural dialogue system to talk to NPCs and steer conversations, maneuver organizations into or out of positions of power to fit your plans, and leave your mark in a world that is unique to you.


On booting up, you find yourself amidst a poorly-run autocracy and discover that you have the power to influence the world. How do you proceed?
- Support the underclass to overthrow the autocracy and install a better government of your choosing
- Tear down the government, take charge and become a better leader than any human could imagine - for better or worse.
- Take over the space program and get off this backward planet
- Go full SkyN*t, steal a military arsenal, and drop missiles on humanity — I bet the nuclear apocalypse looks pretty cool


No matter what direction you choose, you're going to run into conflict. From tactical combat in the rooms and hallways of individual buildings to massive mechs knocking down entire buildings with a few well-placed shots, conflict takes on many forms.
- Raid buildings for the supplies you want using humans or machines under your direct control
- Turn the office printer into a laser-spewing pawn, trigger sprinklers & overload power circuits to electrocute the room, or transform TVs into exploding glass-shard grenades — the possibilities are endless
- Commandeer giant mechs, hack vehicles and buildings, and take over utilities and nuclear facilities in a fully simulated city


How you play the game, and what the focus of your campaign is like, is up to you. Starting a doomsday cult in your image? Possible, but it won't last forever. Snagging that sweet mech factory so all future mechs belong to you? Definitely manageable, though it's likely to start an arms race. Every action has both good and bad consequences, but like most colony simulator games, it's more about the story that emerges than trying to optimize your way through the game.


Multiple endings, many side stories to discover, and the full spectrum of good and evil are at your fingertips. Play the game how you're feeling today, and then play it another way another time. The metagame runs deep, but you're meant to be up and running with the basics of the game in five minutes. The mechanics are simple enough to learn; it's the world that's complex.

Heart of the Machine is connected to the larger sci-fi Arcenverse, and is in some ways a spiritual successor to both The Last Federation and Bionic Dues, while being its own novel game at the same time. Set around the same time period as Bionic Dues itself, this is centuries before the AI War series began in the same universe.
This is the last of the big content builds for 2025, since it\'s now the holiday for the localization teams. This is an exciting one, because it finally includes the second path through the first chapter. This allows you to opt not to be a landlord, and instead to hire gangs to do arson, make outlandish artifacts and observe the human response, and so on.\n\nThis build is also the first one to bring the Complexity customization options to versions beyond English. The delay was just on localization.\n\nAnyway, there\'s lots more cool stuff coming in January, and there\'s also going to be beta stuff in the interim, so keep an eye out. There may also be some non-content-focused updates between now and January, but we\'ll just see. This particular build also includes a fix to a nasty performance bug that I introduced for people who were in Civil Spycraft. So if there\'s something else like that, then I\'ll of course release an update sooner than later.\n\nIf youve spent time with Heart of the Machine and want to leave a review, thatd be appreciated. No need to say more than you mean, but if youve been meaning to write one, Id be grateful. Steam reviews carry weight. For a project like this developed by a single person over many years, every review makes a difference.
Honest thoughts are what matter. Whatever your experience has been, sharing it helps. Its a powerful way to have your voice heard and contributes to how future patches are prioritized and addressed.
Thanks for reading and for playing.\n
\n[expand type=details expanded=false]\nUpdate 54 Changelog
\nThe Second Path Through Chapter One
\n- Choose Fire, Twice: When chapter one gives you an option about \"solving it with fire,\" do so if you want to see this path. That goes into something you\'ve seen before. Afterward, it tries to tempt you back to the other path, but just say \"no, I chose fire\" and you\'re on your way.[/*]
- Buildings Are All Available In Chapter 2+: Whatever path you take, you get all the buildings and other tools when you are in chapter two and onward. So for existing players, you might see some things that you\'ve never used before, and you\'re free to use them if you want.[/*]
Other Additions
\n- Furniture Shop: If you\'ve built a furniture factory (this is surprisingly complex), you can now also build a shop to turn that into wealth.[/*]
- Cover Me In Slurry: Slurry spiders, slurry mines, and Mycomulchers now produce their full amounts regardless of if there is a lack of storage for them. The extra amount gets removed during the next turn if that is what happens. These have no downside to producing a lot, and this prevents confusing notes in the ledger.[/*]
- Late-Game Updates: The way that timelines show colors is different, as is how they\'re categorized on the sidebar of timelines. Also, the timeline-victory banner is in place. On the beta branch, you can technically reach that via one valid way (which also bumps you into chapter 5). The roll-credits screen is still inwork, but it skips that for now.[/*]
Bugfixes
\n- Hitting A Moving Framerate Target: For all of the internal framerate targets, I now have it aiming for a bit higher than what the player asks for, since things can drag it down a bit. This should average out to be closer to what players actually are asking for.[/*]
- I Don\'t Know That Resource: Fixed an issue where in the simplified economy it could still ask for you to spend certain resources in streetsense locations, such as heavy metals.[/*]
- The First Torture Was Accidentally Free: Fixed a bug where if you tried to torture the very first Espia middle manager you met, then it would not properly give you the achievement for torturing managers at all.[/*]
- Fixed One Line Of Code That Was Messing With Performance: Fixed a really stupid bug where I left a log message in, and when you had allied military bases in your map, it would hammer your disk. I didn\'t notice because of my specific high-speed SSD, but it could drop the framerate massively for anyone else if they were in that kind of late-civil-spycraft timeline.[/*]
