The hallmark of The Hell is a very serious approach to development. First and foremost, it is concentrated on getting rid of all the initial bugs of Diablo & Hellfire. It also raises challenge considerably, gives much more variety (monsters, items, spells, boss monsters, unique items, item & environment colors), improves overall difficulty balance of the game, improves monster AI, introduces new character animations, increases replay value and gives full support for Multiplayer experience.
