How it plays
ANEURISM IV is an online multiplayer sandbox set in a decaying city. Each player starts as a Spirit about to take human form and then takes on a role, from a factory-working Prole to a Banker, each with its own abilities. Vellocet says there are no set goals or rules: how you spend your time is up to you.
Players can side with the Cortex to keep order and hold back the Rot, a spreading decay that visibly changes the city; join the Scumbags or Zealots to spread it; or stay neutral and get on with daily life. If the Rot is left unchecked it consumes the city, which then resets.
Day to day you work for credits in factories and other jobs, and spend them on necessities, trade or rent property. You also have to manage your nourishment and sanity. The activities Vellocet lists include waiting for rations, crafting goods, doing laundry, paying taxes and evading the Cortex if you don't.
What it costs
ANEURISM IV costs £8.50 on Steam UK, a one-off price. Steam lists no DLC packs or in-game purchases.
