This was inspired by a question I asked a fellow GM regarding why Murder Servitors didn't grant a bonus to defending against hit and runs or on opposed tests for boarding actions. He said "Basically it's my understanding that they kill everything in sight, no IFF system"
So:
When struck by a critical hit that makes the component unpowered/damaged, the Murder Servitors begin to go berserk onboard the ship, and inflict 1d5 crew damage/morale damage per turn. On a roll of 5 a random component of the GM's choosing becomes damaged/unpowered/on fire/hulled and the ship takes 1 hull integrity damage as the servitors spread out and cause massive destruction. To deal with this, the explorers can either:
A. Destroy the servitors on a successful command test (using modifiers for repelling boarding actions/hit and runs), destroying the component
B. Cause a hard reboot of the machine spirit of the Servitors control matrix on successful Tech-Use (difficulty of +0 or -10), repairing the component
C. Space the affected components for no skill test, doing morale damage and crew damage as per the rules for venting fires on P. 223 (corebook)
