SOMA Enemies (major spoilers)

[kojack]

What is so special about the behavior of the monster at site Tau? Every monster had like special behavior (reaction to sounds/movements, teleports if looking at it..) But the one at Tau seems like a normal monster, Amnesia style.

Spoiler below!

It stops for a bit if you look at it, then it inches closer and closer. Insta-kill on contact. Also, it takes about 5 seconds for it to open a door.

And another thing, when the monster from Tau is chasing me it goes into an error T-Pose, why is this?

Looking at the Tau monster script, it almost seems like some of it's behaviour is faulty. If it detects you and either you are very close or you are moving slowly, it switches to hunt mode (also does that if you hit it with a physics object). I would have thought it should be if you move too fast, not too slow. Could be why it hates me just hiding (I can hear you not moving!).
Or I could be (probably am) wrong.
