Was Playing through Half Life 2 on the Orange Box and after the part where you take down the Hunter-Choppper and get the Revenge! Achievement I took out the guys in the building and went round the back of the building. Then I noticed what I thought was another guard, I zoomed in and saw it was just some guy in a brown suit with a briefcase who stood about a bit and walked out of view. I've played Half Life 2 on my PC and never seen or heard of this guy. I've had a search on google and cant find anything else about this, anybody know what its about?
