I'm outside the Gravity Experiment and cant seem to get past the brute. Any help? Background: Long hall with a Brute standing guard. Another passage leads to a large door into a gravity chamber, another large door into a control room, small door back to long hall. I've gone through the rooms, got the door pass, can fire up the gravity generator. Technique 1: I go to the corner of the halls and shoot the brute, then run towards the large doors. The brute always catches me. Technique 2: I go to the small door from hall to corner and shoot the brute. I duck inside and he cannot fit through the small door. I emptied magazine after magazine into him, no effect. Then I go through gravity chamber, shoot him to get him to chase me the other way while I run towards the big doors. He catches me every time. Technique 3: I get him to the small control room door, then sneak around and try and get through the large door he was guarding. It's locked. There is another room with a "Locked from the Inside" door, but I dont seem to be able to get into it.
