The Death Robot Squad is an aggresive NPC in 60 Parsecs!
They will appear randomly on any planet, and are identically functional to the Space Pirates and the Comunists. When they appear in your ship you'll have to use items or a crew-attributed decision to fend them off temporarily, otherwise if you fail to defend yourself they'll invade the shuttle and you'll get a game over.
They're also featured as the main antagonist in April Angelle's mission "Space Pursuit".
