Gears Beneath the Earth

Pull off the ultimate heist amid medieval tech sabotage.

Underneath the bustling surface of the Kingdom lies an intricate mechanical city ruled by a council of inventors. This clandestine city thrives on clockwork wonders designed by humans, elves, dwarves, orcs, and goblins. When the notorious saboteur, Gavelash, plans to exploit these mechanisms to bring the city above into chaos, the rulers request urgent help from a group of skilled adventurers. Tasked with stopping Gavelash in less than 24 hours, players must navigate the clanking dangers of a medieval-tech labyrinth, confronting traps, mastering mechanical puzzles, and outsmarting clockwork guards in a high-stakes heist that challenges their wit and teamwork.
