Welcome to a game jam where history deliberately goes off the rails!

Imagine a world where history has taken a different path.
An ancient era — Antiquity, the Middle Ages, the Renaissance, the Roaring Twenties...
in which advanced technology appears long before its time.

What if the Romans had drones?
What if knights wore powered armor?
What if the Egyptians built their pyramids with 3D printers?
