Under Isolation it says: "While in Isolated State all the Trooper's Hacking Programs, Skills and pieces of Equipment with the Comms Attack or Comms Equipment Labels or Traits (Hacking Device, Repeater...) are disabled." Does this mean that an isolated hacker cannot be the target of hacking attacks?
But the hacking skill is disabled when you are isolated, i.e. does it count as you have it, which is the requirement for for example Trinity?
To expand on Tox's answer: the requirements of the hacking attacks (Trinity, carbonite, oblivion...) are for the target to be a hacker, not for the target to carry a (functional or not) hacking device. On the profile of the units, it is stated "hacker, (killer/EVO) Hacking Device (plus)"
And as a minor point (because you'd still be interested in when the hacker is Unconscious); the skill "Hacker" isn't disabled by the Isolated state.
Did we work out what happens to Unconscious Hackers? Can they still be Trinity'd? (I think the answer is "No, Hacker is an Automatic Skill and has no effect when in a Null state"...?)
