Evaluation

ANEURISM IV launched on March 11, 2025 and has received a steady stream of major content updates ever since. The catalogued major releases include the First Industrial Update (June 13, 2025), the MISERY map expansion (October 24, 2025), Version 19b: Return to Form (July 16, 2026), and Version 20: Nexus & Rats (September 29, 2026), with a follow-up patch shipped on September 30, 2026 and another feature patch on October 2, 2026 — the same day as this assessment. Vellocet has explicitly communicated what is coming next. The Version 20 release post (September 29, 2026) details a Nightmare map rework ("V2"), subsequent improvements to the Misery map, and eventual completion of the previously announced Genome map. The September 30, 2026 patch notes confirm the team is on a feature freeze while addressing progression and core gameplay concerns, and that work is underway on a rebuilt server leasing system and global cross-server progress saving. The October 2, 2026 patch reaffirms continued active balancing and system work, with the team stating they are "listening" and will "keep working on things." These are not vague promises — the developer has named specific deliverables (Nightmare V2, Misery improvements, Genome map) and described the order in which they intend to ship them. The game is clearly in active development with announced content still to come.

About this game

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.

A Living, Breathing City

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.

No Rules, Only Consequences

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.

Key Features

  • 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.
