Arcade is portrayed as a gaming prodigy who invented a literal first-person shooter (called Murderworld). His sister was killed by Magneto in the bridge explosion in Ultimate War, giving him a hatred of mutants. When Longshot is found guilty of murdering a Genoshan politician, he is sentenced to participate in a reality TV show in which he is stranded on an island and hunted by Arcade. 
As Arcade makes his way through the island jungle, he encounters three X-Men trying to save the prisoner. He dispatches them easily, though, and is about to kill Nightcrawler when Longshot knocks him unconscious. He is last seen being tied to a tree by Piotr Rasputin with some scraps of iron. 
Arcade is equipped with various high tech equipment, given his financial status. During his fight on Krakoa, he is seen to employ an automatic rifle, handgun, sonic emitter, and web fluid ("one of my programmers reverse engineered this thing from some polymer he scraped off a wall in Manhattan").
