Ship of Theseus

Every Reality Changes the Ship

The Theseus is drifting through deep space.
Its reactor is gone. Power is failing. Your crew is stranded.
One experimental system still functions: a prototype drive capable of reaching alternate realities.
Somewhere in another universe lies the technology you need to survive.
The question isn't whether you'll find it...
It's what you'll leave behind.
A Cooperative Procedural FPS

Fight alongside your friends through intense first-person combat against alien infestations, rogue machines, and hostile environments.
Every expedition takes you to a different version of reality.
Locations evolve between visits with new layouts, objectives, enemy encounters, environmental hazards, and secrets. Procedural generation isn't just a gameplay system—it's woven directly into the story of the multiverse.
No two realities are ever quite the same.
Build Your Engine

Every mission offers meaningful choices that shape your run.
Collect powerful upgrades, unlock new technologies, and create devastating combinations as you prepare for increasingly dangerous expeditions and massive boss encounters.
Adapt your build.
Master new weapons.
Push deeper into the multiverse.
Every Choice Has Consequences

Each journey changes more than your own ship.
As the boundaries between realities weaken, you'll uncover mysteries surrounding the Theseus, your missing crew, and the true purpose of the experimental drive.
Some realities can never be restored.
Others may still have hope.
