Faceless (XCOM2)

A hulking sack of flesh and internal chitin, this enemy accomplishes what the Thin man failed to do: perfect mimicry of human appearances. Indeed, your first encounter will be in the new variant of the Terror Mission, the Reprisal Mission. On the field, they will resemble civilians for rescue: when approached for evac, they will change into their true form. With high levels of health, they are a force to be reckoned with, with a surprising amount of movement, and a claw attack that appears to have some amount of reach. As you'll often discover them right in front of the solider who just tried to rescue it, they are highly dangerous traps set out for you. Battle Scanners (unlocked by completing the ADVENT Trooper autopsy) can reveal their true form ahead of time, giving you some room to bring them down: at least they don't use cover, so then it's just a matter of getting enough guns to bear before it makes meatpuppets out of XCOM's units.
