So let's say that I have a Camo marker and a TAG in base to base. A enemy hacker total controls my tag. Is the Camo revealed so that the tag and it can be engaged? Or do they get seperated by as small as possible
Well... the TAG may not enter base contact with the Camo Marker, but the camo marker entering base contact is what cancels Camo state. I think the N4 rules set this up by fixing a rare corner case situation (entering camo state and unconscious at the same time) while not reverting either "entering" to "being" in base contact. Anyway, you're gonna need a judgement call here, I don't think the rules can solve it. The most puritan way of reading it is that the units are Engaged while the Camouflaged unit is still in Camo state. That results in weirdness, I do not recommend it. I can also see a reading how the possessed state fails because the TAG is not allowed to enter base contact and there is no way to prevent it other than failing the skill that causes the state - this leads to an undesired way to play to protect TAGs, so... probably not? I'd argue that since the TAG isn't allowed to enter base contact and the camouflaged unit isn't taking part in any action that results in being in base contact, just consider them to not be in base contact.
