From FFG:
The one unbroken lamp in the ransacked laboratory illuminates a small, slug-like creature wriggling on a glass dish. The notes next to it are covered with a bizarre mix of mathematical formulae and arcane symbols. Suddenly, a thick stream of ichor falls across the notes from somewhere above you. Your blood chills as you unholster your revolver. Something growls at you from the rafters.

Science has gone mad in Forbidden Alchemy, a horrifying expansion for Mansions of Madness that presents investigators with three new tales of scientific horror, plus a host of new components for their existing stories! Beyond the laboratory door, you’ll discover four clever new investigators, two terrifying monster types, nearly 250 new cards, 40 tokens and markers, and six detailed map tiles. This comprehensive expansion also contains never-before-seen rules and components for Alchemy puzzles, Side Effect cards, mutations, crawling hands, and even time travel. Do you dare face the eldritch horrors that lurk within?
Forbidden Alchemy introduces four new investigators to the hunt for clues. While the skilled illusionist Dexter Drake aspires to greater arcane powers, psychologist Carolyn Fern bases her arts in more rational, scientific endeavors. Intrepid cameraman Darrell Simmons is no stranger to the peculiar goings-on of Arkham, and the bone saw-wielding Doctor Vincent Lee may, when in a pinch, find himself reconsidering his sacred oath to “do no harm.”
Each investigator comes equipped with a full array of traits and starting items, ensuring players the ability to customize the character that best suits their play style. Doctor Lee’s “Field Medic” ability, for example, lets him test his Intellect to prevent his fellow investigators from taking damage, while his “Autopsy” ability lets him learn what he can from the corpses of fallen foes! With its expanded range of characters, abilities, and equipment, Forbidden Alchemy further bolsters Mansions of Madness’ already significant replayability.
But the eldritch forces that seek to enshroud humanity aren’t standing idle. Forbidden Alchemy also introduces two new monsters, each with multiple versions. The oozing, slimy Crawling One is a writhing mass of shambling flesh that can spray its enemies with a swarm of tiny worms, but the flying Byahkee is an even more formidable beast. It can traverse the map with ease and will strike without warning, so watch the rafters!
Looking for new challenges? Forbidden Alchemy features three horrifying stories of scientific discovery gone horribly awry.
And with Forbidden Alchemy, the story doesn’t end with the exciting finale. Each scenario contains a brief resolution called an Epilogue, which tells players the full consequences of their investigation. Whether the investigators succeed or fail, the keeper reads this gripping conclusion aloud, wrapping up the narrative and delivering satisfying closure to each tale.
