The hallmark of The Hell is an unbelievably 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.

I'll put it bluntly: not all Diablo veterans will be able to beat the game on Doom mode. It is the HARDEST of Diablo Hellfire mods ever!

I'm also sure that it's THE BEST Diablo Hellfire mod!
