I mean, sometimes the AI turns around, presumably because they heard you coming, so it might be possible to test a situation where an elite is always facing away from you at a particular time.
And although you can tell that certain promethean enemies use promethean vision by the waves you see on your motion tracker, I'm not sure if that really influences their AI either or how to test if wetwork's stealth works against it. --- Is there something about the way I type that makes it sound angry? Maybe it's just something about the way you read.
I've always wondered about AI using Pro Vision; does it actually do anything for them? --- What do I look like, Mr Frank-****-For-Free? No Doe, Hoe? You can't **** with me Thizz iz what it iz -- GT - Spidux
I know it effects them hearing you when you sprint.
From what I can tell, it makes it where you don't have to crouch and walk slowly to sneak up on enemies. (Although you should crouch and walk slowly anyway, because they can still see you just as well when standing up.) --- Underwater Spartans: http://www.youtube.com/watch?v=Djp5dtz02eQ&feature=plcp
