Box art of the Forbidden Alchemy expansion.

Inside abandoned hospitals, secret laboratories, and forgotten cellars, scientists are conducting depraved experiments that will drag humanity to the brink of the abyss. Only a small group of investigators can discover the truth and put an end to these mad plots before it's too late...

Mansions of Madness: Forbidden Alchemy provides players with new investigators for the Mansions of Madness base game, as well as new Trauma, Mythos, and Combat cards for use in any story. Forbidden Alchemy also includes three new scenarios, in which investigators will encounter new rooms, monsters, items, clues, locks, and obstacles:

With four new investigators, two monster types, nearly 250 new cards, 40 tokens and markers, and six detailed map tiles, Forbidden Alchemy introduces a host of new enhancements to your Mansions of Madness experience.

The revised printing of Mansions of Madness: Forbidden Alchemy, released May 2012, includes corrected cards and map set-ups for all three scenarios.
