ai humans are pretty bad in this game,
they're pretty harmless when you fight them on your terms, but the second one argos it will hunt you down to the ends of the earth, make no noise, then mag dump you when you're doing something else. It completely ruins ever being sneaky or trying to get around enemy players, as the ai will hone into your exact location with 0 self-preservation and give it away.
Believe me, stalker's ai is bad, but not this infuriating.
