About ANEURISM IV

ANEURISM IV drops you into a decaying metropolis where you play as a Spirit on the brink of flesh. The game is a sandbox simulator with no imposed objectives, letting you influence, disrupt, or simply observe the world.

You can adopt roles such as Prole or Banker, each offering distinct ways to earn credits, manage nourishment and sanity, and interact with the ever‑spreading Rot. Survival depends on how you choose to engage with the city.

01 / THE GUIDE

Faction Alignment

Players may align with the Cortex to stabilise the city, join Scumbags or Zealots to spread the Rot, or stay neutral and live ordinary lives. Each alignment is described as offering unique abilities, challenges and interaction methods.

The chosen alignment directly influences how the Rot spreads and how other players respond, creating dynamic consequences that shape the city’s overall state.

  • Watch how the Rot reacts after a faction’s action before committing fully.
  • Consider the long‑term impact on other players when picking a faction.

02 / THE GUIDE

Economic System

Credits are earned by labour in factories, managing resources as a Prole, or manipulating finances as a Banker. The description links these jobs directly to credit income.

Credits are required to purchase necessities, trade goods, or invest in property, making work a core loop regardless of the role you adopt.

  • Balance multiple jobs to avoid sudden credit shortages.
  • Investing in property is one documented use for surplus credits.

03 / THE GUIDE

Survival Mechanics

Players must manage nourishment and sanity while navigating an oppressive environment. Eating suspicious things, evading taxes or going insane are listed as possible outcomes.

Survival is presented as dependent on willingness to work, implying that neglecting basic needs leads to failure.

  • Keep an eye on your nourishment and sanity regularly.
  • Test safe food sources before consuming suspicious items.

04 / THE GUIDE

Multiplayer Interaction

Friends can join the same world, allowing collaboration, competition, or coexistence. The description states that multiplayer actions collectively shape the city’s state.

Online PvP, LAN PvP and broader multiplayer modes are listed, meaning any player’s decision can ripple through the shared environment.

  • Coordinate with allies to focus on a single goal for greater impact.
  • Use opposing factions to create tension and observe emergent narratives.

05 / THE GUIDE

City Dynamics

The city reacts dynamically: actions can lead to its downfall, a reset, or maintained order. The Rot visibly alters the city, and roles like Liquidators or Scumbags influence its containment or exploitation.

No preset objectives exist; the city’s state at any moment reflects the cumulative choices of all participants.

  • Track Rot spread as you explore to anticipate areas needing intervention.
  • Experiment with both destructive and protective actions to see contrasting outcomes.
