By setting the game in the surreal world of dreams Ubisoft are able to open the level design, but also fall into the trap of the game feeling like a series of moments, rather than a whole. This 2 player co-op game is drop in drop out local play only. You initially begin the game as Captain Haddock and Tintin. Inside the mind of 'The Haddock' are a series of doors that act as portals to new levels; Mario 64 style. Each level uses the core Tintin mechanics taken from the single player game, but with added co-op gameplay such as the ability to lift one another onto higher platforms.
