Sneaking through nine locations is easy when you are Wario: Master of Disguise. After Wario jumps into his television and takes over the show of an accomplished thief, he must work his way through ten missions to locate more disguises and avoid his pursuer while attempting to locate an ancient artifact that can grant wishes. Throughout the game, Wario must use such disguises as Space Wario, Dinosaur Wario, and Graffiti Wario to navigate through his environment, take down enemies and defeat end-of-level bosses. For example, Space Wario can fire lasers to unhinge platforms, and Dinosaur Wario can incinerate an enemy with his fire breath. At the beginning, only the thief costume is available, but as you progress more become available. You can revisit each of the environments with your new disguises to gain entrance previously inaccessible areas. Along the way, Wario can engage in eight different mini-games to earn the keys for treasure chests filled with goodies.
