After "X-Men: Apocalyspe" promos focusing on the other three of Apocalypse's Horsemen, the fourth -- and presumably final -- featurette has been released. This one focuses on Magneto and sheds more light on the mutant master of magnetism's mission and motives. The featurette follows in line with the other three Horsemen ones, which starred Storm, Angel and Psylocke.
