Walker and crew come across agent Riggs (CIA) under attack from 33rd forces. Riggs speaks of capturing the water supply in order to route out the 33rd. It quickly becomes apparent that Riggs has an agenda of his own, but he is not attacking Walker and his unit, so they go along with it for now…
Delta Squad gets words from Radio Man that Riggs is there to destroy evidence of Konrad and the 33rds deeds. After moving through the Aquatic Colosseum, Riggs and Delta Squad proceed to attempt to evacuate with the water tankers but are attacked. rather than lose the water supply to the 33rd, Riggs purposely crashes the tankers to destroy them. Delta squad is separated as Walker flies through a window of nearby building during the explosion.
