i have an idea how this gamemode would work.
Story: the importers have replicated themselves on the ship and now only 2 crewmates remain
1. crewmates have to do task without getting caught.
2. they can also vent to keep there identity a secret
3. there name would be red among the other impostors, but blue around the crewmates
4. the impostors cant kill.
5 the crewmates can sabotage, coms and lights.
6. if the impostors vote off all the crewmates they win
7 if the crewmates finish all task, they win
