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:
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:
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.
