Looks like Diablo 3 has a second secret level. This time it’s in Act I during the “Shattered Crown” quest and lies within one of the three Defiled Crypts that randomly send you to the secret area called “Development Hell” Jay Wilson, the game’s director seres as an elite monster in the level and has an achievement called “Feat of Stregth” as well. If you want to check out the first secret level, check out our earlier post on the Whimsyshire Level.
