Diablo is a hack-and-slash dungeon crawler developed and published by Blizzard in 1997. It notably features procedurally generated dungeon levels, each with their own themes. It also features three different character classes, namely the Warrior, the Rogue and the Sorcerer. Every class has their own set of advantages and disadvantages.

Arriving in Tristram, the player character receives assistance from various townsfolk. From there, they can descend into the labyrinth from the cathedral, leading to the catacombs, the caves and finally Hell itself, ultimately confronting Archbishop Lazarus and finally Diablo himself.

dwangoAC, ephphatha, staphen and AJenbo abuse the game's dungeon generation code in order to create favourable level layouts. Therefore, they defeat Diablo in record time. Please read the authors' extensive comments for more details.
