Mimics sometimes carry an item in one or both hands, and rarely a guitar or accordion they play while walking, exactly like players do
Mimics occasionally blink their flashlight at you
Mimics now and then glance at the PDA on their wrist for 3-6 seconds, the screen glowing just like a player's
Mimics may jokingly shove you a couple of times when you meet, like a teammate goofing around
Hit a mimic with a bolt and it may answer with a volley of one to five bolts back at you
Bolts now bounce off every monster, mimics flinch like players, and a hit monster turns to check where it came from, though it can't tell how far away you are
In first-person runs mimics now move like first-person players: no walking backwards, eyes ahead instead of at the floor, occasional jumps while running and onto ledges like the handcar
Mimics now drop off the handcar and other ledges with a real fall, instead of snapping to the ground in a single frame
Monsters now go for the closest prey they've noticed and switch mid-chase to one twice as close, so a mimic standing right in front of them is no longer ignored because a player is behind it
In first person the bolt now flies toward the center of the screen with constant strength, slightly upward like a grenade, instead of bending its arc to whatever point you aim at
Mimics no longer fetch every bolt you throw like a dog, and they ignore noise while they can see a player
Monsters that can see you no longer wander off to check a stray noise like a thrown bolt
Mimics bite again when they bump into you, before they could push you with their body without the touch counting
Monsters that walk into the truck after a sound or prey now walk back out on their own, mimics included, before they could get stuck inside for good
Monsters heading for a noise in the truck no longer go deaf on the way and on the ramp, and they run to loud sounds instead of crawling from across the map
Netopyr no longer loops in and out of the truck because of the charger, once it has checked the hum it stops coming back and hears everything else, bolts included
Monsters no longer walk through mimics
A dead mimic's flashlight and held item now vanish, the flashlight used to stay hanging in the air
