Solo, PvE & PvP
Three completely isolated worlds built around different relationships with other survivors.

Current build screenshotThe current build is focused on Solo foundations. PvE and PvP remain planned isolated worlds documented here for direction only.
Complete gameplay isolation
Solo, PvE and PvP are separate worlds. Characters, inventories, discoveries, Safe Houses, economies and deaths never cross modes.
Solo
Current focus Your private persistent survival world, with no other human players.
PvE
Planned Shared cooperative world where survivors can work, trade, build and face the apocalypse together without direct survivor-vs-survivor attacks.
PvP
Planned Shared competitive/cooperative world where other survivors can help, exploit or attack you according to the world's rules.
Account entitlements
Account-level non-power entitlements may persist across survivor deaths, but gameplay state and paid power never cross world boundaries.
