If you love tight combat, smart builds, and runs that feel wildly different every time — you’re home.
Fuse parallel characters, unlock new synergies, and tear through dark sci-fi worlds with speed, style, and precision.
A rogue-lite journey through the multiverse
The various branches of the multiverse are always changing. Fight through a combination of procedurally-generated levels as well as hand-crafted challenges and arenas that will put your skills to the test. Levels with 3D graphics are seamlessly constructed out of hundreds of custom-made rooms.
High-intensity combat
With weapons and attack systems that leverage our previous experience working on fighting games. You’ll slide, dash and dodge between enemy attacks and strike back with an arsenal of satisfying special weapons and abilities.
Three characters, three universes to explore
Each of your parallel selves has their own world with multiple biomes to explore, as well as their own sets of unique abilities and weapons. Travel through a universe of desolate wastes and caverns roamed by mutant creatures, escape the endless forges and labs of a world ruled by machines, and survive the dangerous sky cities of a post-human society.
Constant Progression
Unlock permanent upgrades in the Hub and discover new starting points for your run as you reclaim major locations in each universe. Finding yourself getting stuck in one area? Start your next run in a different one! No matter where you die, or which starting point you pick, you're making progress somewhere.
A Story That Persists Across Runs
The game’s characters and lore are crafted in collaboration with award-winning poet and sci-fi novelist Ada Hoffmann, author of The Outside, The Fallen, and The Infinite.
As the story unfolds, new starting points are unlocked across the multiverse, allowing each run to begin deeper into the journey. Even when a run doesn’t advance the narrative, players earn resources that can be invested in permanent upgrades back at the Citadel — steadily strengthening their characters, expanding their options, and ensuring meaningful progress toward the story’s conclusion.
