"Robotic" enemies are supposed to be vulnerable to EMPs, but it's not always obvious what counts as a robotic enemy, as demonstrated by Are Gatekeepers vulnerable to EMP Bombs?.
For example, the Gatekeeper can be mind controlled, so it's "organic", but it's also vulnerable to EMPs, I suppose because of its robotic shell.
So which types of enemies can actually take damage, or be disabled in someway, by EMP weapons?
