As Twinsen, a young Quetch, the player is on a long journey to release your home world from the domination of the evil doctor Funfrock.
The game combines action and adventure. You must talk to other characters, and collect and use objects. On the action side, there are platform jumps. Twinsen can move in different ways such as 'Sneak' mode and 'Aggressive' mode, to deal with foes in different ways.
The game universe is rendered with characters in full 3D, and the environment using isometric graphic tiles.
