This Xbox exclusive was the fastest-selling game on Xbox Live. Ever. A groundbreaking approach to DLC, Case Zero bridged the gap between Dead Rising and Dead Rising 2, and introduced a new hero in a new world. Chuck Greene was first introduced to the zombie menace, and had his first challenge in finding life-saving Zombrex for his infected daughter Katie. Combo weapons, an innovative story treatment, and a terrifying psycho made Case Zero one of the most talked-about downloadables in years. A solid 10 out of 10 on 1UP.
