No published party XP share, resurrection rules, or co-op-only recipes. Sea activities and vehicles are roadmap items — held. Friendly fire, downed states, and host migration remain unknowns — not assumed genre defaults.

Unknowns

  • Whether progress is host-only or shared cloud saves.
  • Item duplication / trade rules.
  • Voice proximity vs party chat defaults.
  • Dedicated servers, crossplay, PvP, controller support, mods.
