Going through the current missions, these are the ones I find that have the Shasvastii Rule written into them (i.e. Spawn-Embryo state scores): Frontline Quadrant Control Safe Area Supremacy The Armory Transmission Matrix None of these missions have the "Killing" rule, which would stop the Spawn-Embryo troopers from scoring at the end of the game (or, might... that one would need to be FAQ'd since the rules contradict each other). It doesn't seem that counting unconscious troopers as "killed" at the end of a game is the default. Those also happen to be every single "Dominate ZO" mission as far as I can tell. The only missions where it doesn't really work is the "control a console" ones (i.e. those usually have the killing rule, so a Spawn-Embryo touching a console wouldn't control it).
