Something akin to Space station 13.
Most players work in the facility - they need to maintain everything, placate the anomalies, and conduct research.
Then you have multiple antagonist roles working to sabotage the facility, retrieve something, or complete other objectives.
Some antagonists are infiltrators, some are overt, some are mundane, some are supernatural, some are external, some are anomalies trying to break containment.
