Close by him he also has a gun (it's inside of a box in the cargo crate). Thsi gun is a custom Desert Eagle called Big Ben. The name could be a take off of the famous clock tower of the same name or (since it is found near Gorden's body) it could be a reference to Half-Life creator, Gabe Newell, specifically his famous email "gaben@valvesoftware.com" and his corpulent weight.
