LEGO Star Wars

The basic gameplay is action with platforming and light puzzle-solving elements. Players navigate two or more characters through stages, each representing a chapter in a movie. These chapters must be unlocked in a plot-dictated order, eventually completing the entire movie. Characters use different weapons (blasters, lightsabers, crossbows, etc.), and each character type also possesses specific abilities. For example, Jedi can use the force to lift, combine, and destroy objects; robots can unlock encrypted doors; other characters may use a grappling hook to access higher platforms, etc. Some of these abilities overlap (i.e. a problem can be solved in more than one way), though often a specific type of character is required to deal with the situation. In the single-player mode, one player can switch between the available characters; in the co-op mode, two players navigate at least two different characters.

A few levels involve players piloting aircraft, fighting hostile vehicles, overcoming obstacles or destroying targets on the ground. The Free Mode allows players to access previously visited stages with any characters they have unlocked. This may lead to a discovery of previously inaccessible areas. Various collectible items and LEGO studs (which serve as currency) can be gathered during exploration. Characters cannot permanently die in the game; when a character is killed, he or she only loses collected LEGO studs.
