The Missing Experiment

Author: MonkeyDM

Addon: Content which can be added into any game - new or existing!

Price: $5.49

Those Who Try to Defy Death Shall Be Punished

The Missing Experiment is a Fifth Edition adventure optimized for three to six characters of 5th level. Full of terrifying monsters, a Frankenstein's monster-like creation, this adventure is perfect if your table wants to dive into a frightening investigation.

This is a unique adventure, containing twists and turns to surprise your players. Full of Frankenstein vibes, as in the original horror novel, with new monsters from the mad brain of a crazed scientist, and all the things you'd expect to find from a horror story. This adventure is for level 5 adventurers ideally. It can be used perfectly to take a break from your main campaign, as a side quest to an existing world, or to run if your players find themselves in need of a good scare and more tension at the gaming table, or for Halloween if it is that time of the year.

This adventure can go either way, and either reward your characters handsomely or rob them of their sanity.


For the better part of his 50 years, Professor Ordus Bugenheimer has been trying to beat death. Originally an ordinary doctor, Bugenheimer has slowly but surely delved into the world of experimental, non-magical necromancy. But, in his opinion, magic is too flimsy and lacks the ability to give free will to the beings restored to life.
Recently, Professor Bugenheimer has made great progress with his discovery, giving life to an intelligent flesh golem by the name of Hanson. This golem is built with half a brain from a recently-killed bartender named Wilfer Hanson, half the brain of his deceased son, and the flesh of several bodies stolen from the mortuary.
It just so happens that, as the adventurers arrive within Professor Bugenheimer’s proximity, Hanson has disappeared, making the Professor increasingly panicked and in need of adventurers to aid him.


This adventure includes themes and descriptions meant for mature audiences. It can be toned down and used for younger players, but as it stands, it is a horror adventure. It contains: the death of a family member, kidnapping, blood, gore, undeath, flesh horror.
