In Transmission Matrix, can a disconnected Kiss dominate the antenna against an enemy servant? (Disconnected do not count as Null state)
Based on these two lines from Disconnected: Disconnected troopers count as casualties for the purposes of Retreat! Players cannot count their Disconnected troopers as survivors for Victory Point purposes at the end of the game. I would say that no, a disconnected Kiss can't dominate an antenna
Yes, they can. That bolded section is only at end of game and also only to lose surviving points. Otherwise, yes they are model not in null state, which is what matters.
I'm not sure if G: SYNCHRONIZED troops can dominate at all in this mission, judgeing from the DOMINATE ZO's description: Only troops represented by miniatures or Markers (Camouflage, Spawn-Embryo, Seed-Embryo…) count, as well as AI Beacons, Proxies and G: Servant Troops.
Yes, but it represents a G:Synchronised troop wich is not included in the list above (otherwise what would be the point of listing beacons, proxies, servants separately?).
It's solved. Disconnected is not a Null state; you're not counting it for victory points at the end of the game. There is no reason not to count their points. Without an FAQ stating otherwise then yes you can dominate a zone with a Disconnected trooper.
