A dystopian simulator where your choices shape a decaying city. Join other players to protect the metropolis from ruin, hasten its downfall, or simply work in the factories. With no set goals or rules, every action has consequences in a world teetering on the brink.

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.89/day in the week to Aug 4 → 4.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Enter ANEURISM IV, a sprawling metropolis where the proletariat works without question and the air is thick with decay. As a Spirit—a spectral entity on the verge of becoming flesh and bone—you stand at a crossroads. The city is yours to influence, disrupt, or simply observe. With no set goals or rules, how you engage with this world is entirely up to you.
From the hardworking Prole to the affluent Banker, each fate offers unique abilities, challenges, and ways to interact with the city and its inhabitants. Your choice defines your journey:
Align with the Cortex to stabilize and protect the city.
Join the Scumbags or Zealots to spread the Rot and sow chaos.
Remain Neutral and immerse yourself in daily life, working in factories or exploring the city.
An ever-present threat, the Rot visibly alters the city as it spreads. Roles like Liquidators and Scumbags are pivotal in either containing or exploiting this menace. If left unchecked, the Rot will consume everything, leading to the city's demise.
ANEURISM IV is a sandbox simulator first and foremost. The city reacts dynamically to player actions:
Take Down the City: Collaborate with others to bring about the city's downfall and witness its reset.
Protect the City: Work to maintain order and keep the Rot at bay.
Live Your Life: Engage in everyday activities or carve out a unique path—it's your choice.
Survival depends on your willingness to work. Earn credits by taking on various jobs—labour in factories, manage resources as a Prole, or manipulate finances as a Banker. These credits are your lifeline, allowing you to purchase necessities from shops, trade for valuable goods, or invest in property.
In ANEURISM IV, there are no rules dictating your actions. Every decision you make impacts the city and its inhabitants. Will you bring stability or chaos? The choice is yours.
Total Freedom: No imposed objectives. Play your way.
Dynamic Consequences: Every action influences the world around you.
Multiplayer Interaction: Invite friends to join your world—collaborate, compete, or coexist.
Survival Mechanics: Manage your nourishment and sanity in an oppressive, ever-changing environment.

if you make a mistake and kill the wrong person because youre a noob you are stuck as a slave and then must manually press E on 50 boulders until they fall into a pit. No wonder this game has 12 people playing it
I go prole (neutral fate) and pull out the 9mm I got while I was playing scum (non-neutral fate) and use it to walk up to a liquidator (neutral fate) whose sole objective is to keep the scum (not me, I’m a neutral prole remember) from rotting the server (non-neutral outcome) and neutrally blow his neutral brains out. I face no consequences for this as that would imply an lack of neutrality in anything I just did. Fun game

Fun when it came out. That didn't last long. Now it's empty. No sense buying an online game with no players.
Used to be fun but the developers are going in 10 different directions all the time
Tired of the pk, grinded to become a cop. Another cop combat baited me with the limitation system, killed me, and sent me to the underworld with -16 cytes. Can't recommend, too much pk. In the spirit this game was intended, don't buy unless on sale.
A game with potential that rewards toxicity and punishes justice Your only way to survive is unfortunately to make someone elses day worse, and you are not allowed to fight back if someone does it to you. Its a broken system, that wants you to be as toxic as others to win. You cant be passive, you cannot enact your own justice, you can just be toxic. There is only fun for those who are already fatherless
Every time I open this game I remember the first time I played it. The whimsy and wonder I associated with Anuerism and its world. I felt like I could do anything, be anything I wanted to, but I haven't felt the same since then. Anuerism used to feel alive, and now it feels dead. All anyone does is be ♥♥♥♥♥♥♥♥ to each other and if I'm being honest hopping on and playing anuerism at this point just makes me sad. It makes me sad that the potential this game had was lost. It just feels like a waste of my time as a player who plays cortex/banker. I'm constantly getting ratted out, karma killed, or gangbanged by proles and scum as banker. This game certainly had potential, the peak on steam charts shows over 1k players, but the playerbase dwindled down after the updates for that exact reason: its a waste of time. Especially the way the game is designed now. Maybe in some years I'll come back and things will be fixed but with the current state the game is in I don't have much hope. At the current state the game is in I wouldn't recommend buying it, playing it, or wasting your time. There are much better things to do than to live in Anuerism With that being said it hurts to leave a negative review. I loved this game and all the silly things that came with it, and yeah a large part of that was people being ♥♥♥♥♥♥♥♥ to each other. I feel as though its reached a point where its unrecoverable. I want to be able to play anuerism again and make content off of it but I can't when Its just rat central. Why waste an hour or two grinding amns and doing wartime to become banker when I'm just going to get shot or stabbed by the first person I see after I switch? Why even waste my time writing this? To prevent people from making the same mistake. Don't play this game, you will probably regret it. 1/10 I hate that you guys ruined one of my favorite games (I wish they would remove scum from the game entirely)
devs got such a massive launch and just let it rot away to pursue another pump and dump indie game which won't nearly get the same attention A4 got. I haven't played since preview launch and it's clear to see how the devs just dgaf anymore.
Popped into a server that I had zero minutes of playtime in. Someone gave me a pickaxe so I could murder a singer outside of the laundromat and paid me afterwards. I then go mad with bloodlust and murder 3 miners, and a doctor that teabagged one of them. I then chase another man to a square filled with people surrounding 2 cops, at this point I have gained an accomplice. I give in to the bloodlust and attack an officer and incite MOB VIOLENCE IN THE CROWD. I die screaming revolution and become a slave. I alt F4 and play a different game.
Honestly sad to say, but the devs are running the game into the ground. None of the updates seem to actually fix any of the issues people have with the game and the low player count is a testament that. You will literally only find one server with enough people to be playable (more than 3) and it's very much not worth the money with how it is now. The game used to be fun to play, now it feels like you need to have no life to be able to actually get anywhere in the game. Devs seem to hate the players for some reason. Also devs are working on a new game so rip.
