The player takes on the role of a mustachioed uncle who has been kidnapped by an evil entity. The goal is to guide a protagonist, who is trying to rescue the uncle, through a series of increasingly complex environments.
The gameplay centers around moving the protagonist from one side of a level to the other using movement keys. The protagonist can shoot a grappling hook to traverse across gaps and climb on top of obstacles. The player must time the hook releases carefully to avoid falling off or colliding with enemies.
The objective is to find a way to reach the uncle and free him from captivity before running out of lives. The game challenges the player to master the grappling hook mechanics to overcome obstacles and find the hidden path to the uncle. Expeditions can be played directly in the browser without the need for downloads or registrations, offering an immersive gaming experience.
