Unlocking The Forgotten

[Nekkid Grandma]

Anyone have any good strategies for unlocking The Forgotten? Been trying to help my sister unlock it in online multiplayer, I've gathered that using Azazel is the best character for it, or at least I assume for the one holding the shovel piece, but beyond that it is becoming a real pain to get it done.

It's about clearing rooms quickly and getting to the boss rush as fast as you can, so Azazel probably is the best choice because he flies. I think I did it with Cain, but you really just need a character you're good with.

Go to your item room, then the boss and down to the next level. Don't spend more time on floors than you need to so you avoid getting hit more. The person with the shovel piece has to constantly move in a particular way, avoiding turning back the way they just went, kind of like the game Snake. This is especially important on the boss rush since you'll be in there a while.

I don't really know if it's made easier or harder on multiplayer.
