Well,I got the achievement when I typed "disable106" in the console.Nightmare Tank wrote:Actually, I did this before the screen went black as well. Everything went smoothly, The Old Man did not chase me down, yada yada yada. He was pretty much caught.
However, when I took Gate A out of the facility, it re-appeared out there and I got the Chaos Insurgency ending. The achievements also claimed I didn't contain it, even though I did everything right and it didn't come after me following the recall procedure.
When you contained 106 it should not appear at Gate A,but I think it got bugged.
