Diablo is an isometric strategy RPG and one of the most well-known examples of the action-RPG subgenre. Although some of the game mechanics resemble a typical RPG, all actions are done in real-time just like in an action game. The player have to kill hordes of monsters through randomized dungeon levels in order to gain experience points, gold and a variety of equipment to bolster the hero's monster-killing potency.
