About Expedition to Madness
Expedition to Madness is a 1–4 player co-op cosmic horror experience that blends survival, exploration, and psychological tension. Step into the boots of an inter-dimensional explorer on a desperate mission to find your missing partner, Emily—lost somewhere in the folds of reality.
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. Maintain the wormhole. Discover what happened to her… and what lies beyond.

Key Features
- 1–4 Player Online Co-op: Venture alone or with up to 3 friends. Every run is unique.
- Multiversal Horror Settings: Explore shifting dimensions based on Lovecraftian literature, fully rendered in atmospheric first-person.
- Resource-Based Survival: Balance your energy consumption/gathering, and sanity as you extract primordial energy to avoid being trapped in the void forever.
- Narrative Discovery: Uncover Emily’s fate through journal entries, strange phenomena, and clues across worlds.
- Lovecraftian Enemies: Face creatures that defy logic—some you can run from, others you must challenge… or avoid entirely.

- Nonlinear Objectives: Choose how to explore, what to extract, and when to escape—if you still can.
