5. Alice: Madness Returns' Dollmaker's Workshop
The deeper meaning behind this level is necessary to Madness Returns' plot, but you'll probably wish you didn't know the implications of Alice's demented fantasy. This stage is already one of the series creepiest, given that its a trip through a grimy, rust-colored factory that churns out cracked, disfigured, sometimes murderous porcelain dolls. But when boiled down to its horrifying essence, the Dollmaker's Workshop is basically all about child prostitution, which has to be a first for video games. American McGee, you are one brilliant and messed up dude.
In Alice's waking life, she receives psychiatric treatment from Dr. Angus Bumby, who also runs the Houndsditch Home for Wayward Youth. His methods initially seem to help Alice, but her subconscious eventually unravels what's actually going on. The reality is that Bumby is brainwashing young orphans with hypnotherapy, then covertly peddling them as sex slaves on the London streets. This abominable situation manifests itself as the Workshop in Alice's mind, with a warped version of Bumby (with rivers of tar continuously oozing out of his eye sockets) as the controlling Dollmaker. Just like the Dollmaker manufactures hollow, damaged dolls, Bumby is producing mentally traumatized, doll-like children in the awful reality.
