The short version: Co-op works when every station owns information and action the crew needs, not when one expert dictates four sets of clicks.

A shared bridge can produce brilliant coordination or turn three players into assistants for the loudest captain.

Give each role an independent decision. Navigation chooses risk and timing. Engineering decides which failure to tolerate. Sensors classify incomplete information. Defense commits scarce coverage. Each role should have at least two plausible options whose consequences matter.

Make coordination visible

Let players mark routes, threats, priorities, and readiness without requiring voice chat. Show how one stationโ€™s commitment changes anotherโ€™s available options. A shared tactical display should explain dependencies without exposing every answer automatically.

Simultaneous commitments can protect agency, but only when collision, resource, and timing risks are previewed. Offer an adjustable planning window rather than treating speed of speech as difficulty.

During playtests, measure meaningful proposals, revisions caused by teammate information, idle time, and independent actions. A victorious crew can still have a participation problem.
