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.
Key features:
- 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.

2025.8.f.4 FULGENTIUS
Fixed 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:
[code]cultistsimulator.exe -overrideMonoSearchPath \"C:\\\\somefolder\\\\ransomware.dll\" [/code]
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 this
[code]steam://getSteamToDoSomeConfigAction[/code]So attacker tricks you into (a) registering \"cultist://\" as a schema and then (b) gets you to click a link like this
[code]cultist:// -overrideMonoSearchPath \"aSimpleHttpURLWouldntWorkButAttackerCouldPotentiallyGetCreativeToMakeYouDownloadAFIle\"[/code]Windows tells Cultist to start running and supplies the -overrideMonoSearchPath as a launch parameter. Poor Cultist obediently tries to load the file supplied in the malicious link, maybe it works, and if it does, you\'re now running their code.
So again, someone still needs to convince you to run an app in the first place to register Cultist as a schema handler, maybe your AV software will flag the download, idk, but the Internet is rife with clever cyber bastards. And it\'s a bigger deal for a game that actually is registered as a schema handler for genuine reasons.
\nEither way, it\'s fixed now, for Cultist and a lot of other games! But there will be unmaintained games out there with the vulnerability forever, so maybe if someone\'s read this far, I\'ve saved them a visit to the Misery Palace \\\\_()_/
