Disgraced heavyweight boxing champion Arno The Overgrown was discovered by Guerrilla Warfare (GW) Trappers living out of a cave. Over time, Arno became an expert survivalist and big-game hunter—capable of living off the land indefinitely with just his flint stick and sharpened hunting knife. Rumors of Arno eventually spread to nearby townships, drawing the attention of Guerrilla Warfare (GW). Hoping to recruit his unmatched hunting and fighting skills, GW tried to lure Arno out of his habitat, but failed—until they threatened to stop visiting him each month with hot, fresh Milk Tarts.
