Madness

Oh no, you've succumbed to the Madness of the Abzu depths! The Neon Deepwater Research Facility is home to many exotic things: plasma reefs, large jellyfish, and horrors beyond your imagination. When one of the mysterious megafauna of Abzu buzz the facility, some crew members may break under the pressure. They will temporarily get an objective to work against the station, such as destroying a department or killing one of the station's cherished pets. Station security may end up detaining people afflicted by madness until they're no longer afflicted, and Haloperidol is a potent anti-psychotic.

Unlike other Antagonist roles, you must stick to your given objective - one cannot bend the madness to their own goals, but must instead serve the madness.
