It’s hard to describe all the ways our AI are going to become more sophisticated in 1.07, mostly thanks to grayman. AI will now properly notice and comment when suspicious doors are left open. They’ll notice rope arrows left dangling in lit areas, and will come over and look up or down the rope to see if anyone is on it. AI will notice if arrows are left sticking out of things (and will no longer call them “weapons”, or comment casually after getting shot with them).
AI will do a better job of warning each other about suspicious events now too–if an AI sees the player but fails to catch him, he’ll warn all his friends that there is a thief in the area. If he sees a dead body, he’ll start warning people about a murderer. This causes the friends to start patrolling with their weapons out, ready for trouble. All the new interactions make the AI seem even more believable and challenging.
