In the game, the player uses Scooby-Doo to take down enemies and collect clues for Velma. Scooby-Doo can change costumes which can give him different moves such as kung-fu and fly like a bat. Without using these costumes some levels may not be possible to finish. This is the third Scooby-Doo game to feature a laugh track. In the Nintendo DS game, there are a few minigames included to make use of its touchscreen. Source: Wikipedia, "Scooby-Doo! Unmasked", available under the CC-BY-SA License.
