The Great Smog is a Multiplayer Co-Op Steampunk Horror that blends the group scares and legendary enemies of Horror Hunters with the player-driven gameplay and reactive world of Immersive Sims.

You and up to 3 friends will descend from your Airships, customizable bases far above the dangerous streets, into iconic London locations in order to defeat their mutated inhabitants and collect resources to upgrade and adapt your gear.




Explore the abandoned ruins of the jewel of an empire at its height of power - a London on the cusp of revolution both technologically and politically - now a haunting, desolate wasteland.

Delve into its many landmarks to collect resources, encounter terrifying mutants and uncover the secrets behind the mysterious Great Smog.





The London of the Great Smog is a vast, sprawling city with many possible areas to explore. Each map has semi-random loot locations, unique and rare loot, and variable mutant types, giving you ample reason to return.

Factions such as the Trade Unions or Aristocrats will offer additional Contracts, optional objectives that can vary from collecting extra of a particular resource, to unlocking hidden areas in levels and completely changing the players' mission.





Players will be able to customize everything, from their character's appearance to the furnishings of their airship and the wood grain of their rifle's stock.

Whether it's through stealth, shooting, luring mutants into a trap or cleverly adapting the environment - you are free to take on the streets of Steampunk London however you choose. Tackle problems in any way you see fit, and navigate levels through multiple routes, all fitting your unique playstyle.





Make strategic choices about which resources to prioritize, which new item to craft or which faction to do contracts for in order to survive the hostile world of The Great Smog.

Managing your resources effectively and planning your next steps well will mean the difference between life and death.





When you first descend to the Smog-ridden surface, you will be woefully unprepared. Only cunning and willpower will keep you from being at the mercy of the horrors that lurk in its alleyways.

But with dedication and ingenuity you can learn, adapt and improve. Eventually, you and your friends will rise to the challenge and go toe to toe with foes that once seemed insurmountable.
