player versus player has been implemented in Diablo III using unique arenas designed with differing amounts of terrain and cover. Players participate in PvP choosing from their existing characters, with access to all of the gear and skill they have gathered from playing the game in single player or cooperative mode. There will be both ranked and unranked gametypes. When participating in ranked games ('best of' match series), players will earn points for advancement based on how many kills they acquire throughout matches, accomplished objectives, victories. The points earned lead to multiplayer achievements, titles, and other rewards.[28]
