Diablo IV is an upcoming dungeon crawler action role-playing game developed by Blizzard Entertainment, the fourth title in the Diablo series. Series features such as re-playable, procedurally generated dungeons, and loot-focused character-building are returning, while new features such as an open world, and player versus player (PVP) interactions are incorporated. Four playable classes have been announced – Barbarian, Sorceress, Druid, and Rogue – all of which have appeared in the series. Players guide their character through quests and combat in the world of Sanctuary as the once banished Lilith returns to wreak havoc.
