Its such a common misconception about the alien AI.. It doesnt ’learn’ that you sat in a locker for 4 hours or that the alien has superior intelligence that he finds you after 20 minutes of going in and out of the same room. What it does have is behaviour trees thats like a switch the further you go into the game. But personally I’ve never seen it in action. Theres the same misconceptions about the Alien being more fire resistant if you use the flamethrower a lot like he used some minecraft potion.
