The Mad Phantom introduces a new invader species to the game, with its own figures, tokens, and specific event cards. It also introduces a new game mechanic - character madness.

All is calm and quiet in outer space. Except Nemesis. The spaceship's corridors are filled with the sounds of screams, gasps, gunshots, and sparking electricity. MI's dispassionate cameras see crew members shoot walls, scrape their faces with ten fingernails, and cut their own veins. The AI ​​doesn't understand what's going on and why the humans aren't listening to it. They fight about monsters and horrors lurking in the dark. The AI ​​searches the entire ship, but finds nothing unusual aside from a few piles of biomass. Maybe you should burn the humans?

Can you survive the battle with your mind?

Only an add-on, not a stand-alone game.
