ZyMedBio Corp is a pharmaceutical development company. The company is relatively new, having been incorporated just three years ago. In the last five months, the company has begun drug trials on human subjects for a range of clinical issues.

What the Critics Say
"The scenarios in Petersen’s Abominations are every bit as dangerous as those he wrote for Shadows of Yog-Sothoth in 1982, and every bit as enjoyable... Chaosium does it again, and offers us a marvelous supplement for our insatiable Call of Cthulhu appetites."—Reckoning of the Dead.
"A great opportunity for a Keeper to entertainingly TPK his group while everybody has fun."
—Antonios S., RPGNet review.
"Bite-sized investigations, with a creepy modern feel dripping with imagination and blood in equal measure."—Tabletop Gaming UK Magazine
