About this game



Cultist Simulator is a game of apocalypse and yearning from Alexis Kennedy, creator of Fallen London and Sunless Sea. Play as a seeker after unholy mysteries, in a 1920s-themed setting of hidden gods and secret histories. Perhaps you're looking for knowledge, or power, or beauty, or revenge. Perhaps you just want the colours beneath the skin of the world.
In this roguelike narrative card game, what you find may transform you forever. Every choice you make, from moment to moment, doesn't just advance the narrative - it also shapes it.
Become a scholar of the unseen arts. Search your dreams for sanity-twisting rituals. Craft tools and summon spirits. Indoctrinate innocents. Seize your place as the herald of a new age.

In this 20-40 hour game, you'll:
Combine cards to tell your own story in a rich, Lovecraftian world of ambition, appetite and abomination. Corrupt your friends. Consume your enemies. There is never only one history.
Found a cult, dedicated to the Red Grail, or the Witch-and-Sister, or the Forge of Days. Recruit Believers and promote them to Disciples to serve as burglars, researchers, cat's-paws. Use your disciples to keep you fed - or feed on your disciples.
Unravel arcane, unacknowledged mysteries. Translate grimoires and glean their lore. Locate and pillage the Star Shattered Fane. Penetrate the realm of the Hours, and win a place in their service. Perhaps - if you are very cunning - you may even glimpse the Mansus.
Outwit rivals, investigators and the increasingly suspicious Authorities. Your own altered Appetites may force you to act abominably, but your Cause must not be stopped.
Transcend death with a story-driven legacy system. Perhaps your inheritors will complete the Rite of the Crucible Soul. Perhaps they'll find peace in a pleasing career. Perhaps they'll bring the Dawn.

Update 2025.8.f.4 "FULGENTIUS"
2025.8.f.4 FULGENTIUSFixed a bunch of Steam Deck issues that slowly accumulated over time (and resulted in Steam Deck version becoming effectively unplayable).In-game input hints now properly update once the relevant keybinding changes.Consistent font size for all input hints.The Mansus screen can be navigated with the keyboard.Fixed some errors in Russian localisation.Fixed the incorrect display of certain alphabetic characters.Unity security update.So this is another round of Chel's usual crypt-keeper updates. But the headline points are(a) Steam Deck controls now work properly again, sorry! - and(b) an apologetic security update from Unity!--I'll talk briefly about the security update, because you've probably seen, like me, a steady flow of updates in your Steam library, and most people are a bit vague about what it entails.The short version: it's a vulnerability that seems to have been in Unity since 2017, but no one seems to have noticed or used it because it's pretty niche. So you probably dont have much to worry about even in unpatched games. The long version: I'm not a cybersecurity bloke, but broadly as I understand it, here's how it worked. There were command line flags in any game built with Unity that could be used to tell your game to load arbitrary code, for example:cultistsimulator.exe -overrideMonoSearchPath "C:\\somefolder\\ransomware.dll" Of course someone has to (a) get the code on to your machine or a local network path, then (b) convince you to run the relevant command line, which isn't straightforward. But on Windows, it's quite easy to register an application to open any URL in a specified format, like thissteam://getSteamToDoSomeConfigActionSo attacker tricks you into (a) registering "cultist://" as a schema and then (b) gets you to click a link like thiscultist:// -overrideMonoSearchPath "aSimpleHttpURLWouldntWorkButAttackerCouldPotentiallyGetCreativeToMakeYouDownloadAFIle"Windows tells Cultist to start running and supplies the -overrideMono...Read full article on Community Announcements (AK)AnnouncementsOfficial

The Skeleton Light
"It's not a loop - it's a spiral!" That's Alan Wake, in Alan Wake 2. If you try to attribute the quote in the normal way, you get this: "It's not a loop - it's a spiral!" - Alan Wake, Alan Wake 2 which looks ineluctably like a typo. Anyway, spirals. Tomorrow is the seventh anniversary of the release of Cultist Simulator. A couple of thoughts about how we got here from there, and how we got there from somewhere else. When I started making Cultist, I'd never coded anything in Unity at all. hadn't done any actual coding since I built the Fallen London CMS (once nicknamed 'Jonathan' and later rechristened StoryNexus). Once that was up and running, I focused on writing interactive narrative inside that CMS. Which did have loops, ifs, variables, a lot like a programming language - but a very soft-cornered, simple, limited one. {STEAM_CLAN_IMAGE}/31397842/7332344dc49616e9c7e256ed4722a517e823c513.jpg It occurs to me that it might seem odd for a programmer to go from using a versatile and powerful programming language to using a soft-cornered, simple one. One reason is that I wanted, from the start, to build a system that let a team work on expanding a big organic narrative - hence 'storylets' - and I knew that most people who wrote for Fallen London wouldn't be programmers. But there are two other reasons I want to talk about. {STEAM_CLAN_IMAGE}/31397842/8f55699b63712060abe064c11f6c79dffefa359b.jpg The first is that I like the player to be able to build a mental model of what's going on inside the game. Game mechanics can be poetic, in the way a skeleton watch is poetic. If the framework is simple, or even elegant, you can make that poetry visible by making it visible through an interface that works like clear glass - or at least a translucency through which you can see the glow of differently coloured lights. The second is that the constant shift back and forth, between the writer-designer's stance and the coder's stance, makes one's brain ache. Ambiguity, surprises, the u...Read full article on Community Announcements (Arabella Dusk)Patch NotesOfficial

Spanish and French available in beta
“The language is knotty, poetic, wilful. It'll take some untangling." Hello cultists! It’s been a while, but we’re back with our promised new translations for Cultist Simulator. The game and all its DLC are now fully available in French and Spanish. Both languages are currently in beta here on Steam, and we’ll release them fully (i.e. tell Steam French and Spanish are **officially available**) early next month, after we’ve had some time to test them against the scariest Foe there is: YOU. From today’s update, anyone whose OS is set to use French or Spanish will automatically have their chosen language selected when they load up Cultist Simulator. But anyone can select any language from the ‘Languages’ button on the main menu. (So French and Spanish speakers can always switch back to the original English if they prefer, too.) {STEAM_CLAN_IMAGE}/31397842/229c5b36d8bf52cafa526410cb5d2242c2e8ea2d.png Players are the best translators because so much of Cultist Simulator depends on beautiful language and specific, referential lore. So if you are fluent in either French or Spanish, we’d love you to play the game in its new form and let us know if there are any oddities or errors. If you find any typos or mistakes or have any other feedback, please send them to support@weatherfactory.biz. There may occasionally be matters of opinion (for example, which specific translation is the most appropriate for an original English term), but player feedback from people who really get the game and the lore is always incredibly useful. Thank you! The beta will last for one month, before launching fully in early June. Thank you for your patience, and French and Spanish speakers, we hope you approve!Read full article on Community Announcements (Arabella Dusk)
