Blizzard delivered the finale to "Diablo III" on March 25. The expansion, "Reaper of Souls" (RoS), closes out every bit of story that began in "Diablo III." Players return to the Pandemonium Fortress of "Diablo II" to fight the Angel of Death, Malthael, in order to bring an end to the rampant slaughter of man by the newly corrupt archangels. With fantastic storytelling and new skills, equipment, environments, enemies, game modes and playable classes, RoS succeeds in every facet required of a great expansion.
