Mark Vincent was an inmate at the Fiorina "Fury" 161 Class C Work Correctional Unit, one of several who stayed behind after the facility was officially closed down by Weyland-Yutani. He was involved in battling a lone Xenomorph that was born in the prison in 2179. Vincent was killed acting as bait during a desperate attempt to lure the Xenomorph into the lead mold at the foundry alongside the prison.
