Cliff Hudson was a mentally unstable boss from the videogame Dead Rising who was convinced he was fighting
in the Vietnam War - seeing others as enemy soldiers he fought a vicious battle using his machete and years of combat training but sadly died regardless, his death scene is one of the more potent and tragic scenes in the game as he explains the reasons for his behavior, having regained some sanity - his granddaughter had been killed by zombies and he lost control, getting flashbacks of the war and as he took his last breath he commented on how to him the war had never truly ended.
Frank (the game's protagonist) listens to Cliff's story and respectfully closes the dead veteran's eyes before leaving him.
