- Use campaign co-op for shared objective progression.
- Use local shared or split-screen when players are on one device.
- Use online PvP when the goal is competitive Arena play.
Assign one co-op objective caller
- Read the briefing together.
- Choose one player to call objective completion and route changes.
- Avoid triggering extraction while another dependency is incomplete.
- Regroup before entering a new objective area.
- Confirm the result screen before changing the plan.
Check current hotfixes before blaming the network
Replicant D6 first addressed active-lobby crashes in v1002, then temporarily changed hot-joining in v1015 so players queue for the next match while desync and crash causes are investigated. v1026 later fixed invisible lobbies, and v1031 fixed a host-death crash in co-op missions involving Dana.
Verification boundary
What still needs live verification
This is a dated independent guide answer. Update-sensitive mechanics, values, availability, and interface paths can change; the current live game and official announcements remain final.
Official descriptions establish stable scope. Interface paths, balance, values, rewards, schedules, and version-specific behavior must still be checked in the current game build.
