Development Hell is a new way of showing the credits, it is a rarely spawned level that features a group of zombies with the names of the Diablo III game developers.
"Development Hell" is a reference to Development hell, an abnormally long period of development for computer games or other various forms of electronic media.
Location[]
Development Hell is found in the Cemetery of the Forsaken in Act I of Diablo III, as one of the Defiled Crypts. It will appear as a fourth accessible passage, as opposed to normal three, and will have the Development Hell name instead of Defiled Crypt.
The chance for it to appear is very low (roughly 1%).
Monsters[]
This crypt features a variety of zombies: Ravenous Dead, Retching Cadavers, Hungry Corpses. All monsters have the names and jobs of the game developing group. Two unique monsters are present in this dungeon: Jay Wilson and Josh Mosqueira.
Unique rewards include Transmogrification-only swords, Incinerator and Rancor.

Killing Jay Wilson grants a hidden achievement; "Smash, Jay, Smash", placed in "Feat of Strength" group on the achievement page, plus a sigil of a horned demon.
