I am, the game boosted me to hard mode. The AI isn't smart, its cheap. They have a 6th sense for you. Its impossible to sneak up on them. I can understand the ganging up and rooftop headshots since i'm on hard, but if I climb a building that they're on and they're looking the other way the instant my hands touch the roof they all turn around and lob grenades till I either A) fall off the building or B) come up where I will then proceed to get barraged with bullets, and this happens EVERY GODDAMNED TIME . Plus the pedestrian AI is off as well. Countless times i've seen them run into explosions or get in my way resulting in me getting killed. Which would normally be okay, but not when you're going for a hero ranking.
Maybe S.T.A.L.k.E.R. has spoiled me in the AI department.
still tho, this is a nit-pick, and does make it a bad game. its just annoying.
