I think this is a really good idea, but as many people have said interfacing with electrical equipment on the station could be a bit overpowered and would definitely make it a lot harder to hide/run from the terminator, also, how would the terminators be able to infiltrate the staff? In the terminator series, teleporters require the person to be completely naked, so I think it would be very very hard for the terminators to silently slip into the crew as they'd be naked, and would lack an Identification card, immediately making the terminators stand out from the rest of the crew just the same way Wizard and Ninja does, though I really do support this idea. I just feel that it would be way too challenging for the Terminators, but your aim may not even be to infiltrate the station, it really depends on how you're viewing it. If there was some sort of system that the terminators could infiltrate the station without alarming anyone, then it would truly be like paranoia, as you said it would be similar to. Another suggestion would be to perhaps include a large bunch of the crew, for example, the future leader/leaders could have a few unknown supporters, which would most likely see the death of their friend a martyr for their cause, and would take up their work, including more people that need to be protected/killed. Apart from these minor details, I think this is a really good idea for a game mode and would enjoy playing it. (One last suggestion, if people attempt to interfere with the terminator's assassination/protection they are seen as a threat and could possibly be included in to the gamemode, it's up to you how they would be included perhaps)
