About this game
Expedition to Madness is a 1–4 player co-op Lovecraftian investigation horror game where you enter unstable dimensions, study impossible phenomena, identify the entity haunting each world, and decide how much longer you dare remain.
You are part of an inter-dimensional expedition searching for your missing partner, Emily, lost somewhere beyond the folds of reality. Each mission sends you through a wormhole into a corrupted world filled with signs, anomalies, and ancient intelligences that do not want to be understood.
INVESTIGATE
This is not just about survival.
Study the environment. Track manifestations. Gather clues. Compare evidence. Determine what kind of cosmic presence has taken hold before it is too late.
Every dimension hides its own logic, its own threats, and its own truths. Misread the signs, and your team may not make it back.
EXPLORE
Traverse unstable wormholes into terrifying parallel dimensions inspired by Lovecraft’s most iconic stories. From the icy ruins of At the Mountains of Madness to the cursed coastlines of Innsmouth, each mission takes you deeper into a multiverse of horrors and hidden truths.
EXTRACT
Collect primordial energy, recover ancient artifacts, and piece together clues from Emily’s scattered journal. But be warned: unspeakable entities hunt in the dark, and the deeper you go, the harder it is to return.
ESCAPE
Survive the unknown. Stabilize the wormhole. Discover what happened to her and escape with what you found before the dimension collapses around you.
Some entities can be avoided. Some can be resisted. Some should never be approached at all.

The Demo Returns on May 15 — A New Lovecraftian Investigation Experience
The public demo for Expedition to Madness will be available again on May 15.Over the last few months, I took the demo offline to rebuild one of the most important parts of the game: the investigation experience.Expedition to Madness has always been about cosmic horror, ancient gods, and exploring hostile dimensions, but the balance was not where I wanted it to be. Before, the experience leaned more heavily toward finding and extracting primordial energy, while supernatural investigation played a smaller role.That has now changed.The game is becoming much more focused on what makes this world special: investigating the presence of an ancient Lovecraftian entity, provoking responses, gathering evidence, and identifying what is really haunting each dimension. Energy gathering still matters, but it now supports the mission instead of defining it.What has changed?The biggest addition is a brand-new portable investigation scanner.Previously, many of the game’s systems lived as overlays inside the helmet, and most evidence was passive. You often had to wait for something to happen. I wanted investigation to feel more deliberate, more active, and more tense.The new scanner now puts those tools directly in the player’s hands and pushes the experience much further toward true paranormal field investigation.With it, you can:search for blood symbols with a UV scanner and analyze them for cluesdetect voices from beyond reality with an integrated directional sound scannerproject a distortion matrix to glimpse into overlapping dimensions and reveal hidden anomaliesuse synthesized tracking frequencies to locate disturbancesscan for primordial energy sources with a V-Radarnavigate using the map now integrated into the scanner itselfMoving these systems out of the visor and into a multi-use handheld tool has opened much more room to improve the overall evidence-hunting experience and gives the investigation loop a much clearer identity.A stronger Lovecraftian identityLast year I over...Read full article on Community Announcements (terrotide42)Patch NotesOfficial
