Ace used to work as a driver and mechanic for Faran Brygo who sent him to recruit some good fighters for bolstering the defenses of Las Vegas after losing Max. He was rescued by the Desert Rangers in Quartz and recruited into their organization, continuing to serve with them after the destruction of Base Cochise.
Over time, Ace reached the rank of Captain and many younger Rangers looked up to him. He also developed a romantic relationship with Angela Deth. Ace was supposed to retire in 2102 and a retirement party was planned in his honor. His last assignment was finding the source of a mysterious broadcast threatening the Rangers. While travelling he met Samuel Haas, a Snake squeezin salesman who decided to tag along with him.
After attaching a repeater unit to the radio tower north of the Ranger Citadel, Ace was attacked by one of Matthias' synth. Both of them were grievously injured in the ensuing fight and eventually died while trying to crawl away from the encounter site.
