Flat Zone (フラットゾーン, Flat Zone) is an unlockable stage in Super Smash Bros. Melee, and the home stage of Mr. Game & Watch. Flat Zone is unlocked when the player beats Classic Mode with Mr. Game & Watch. In All-Star mode, Flat Zone appears as the last stage where the player faces 25 lighter Mr. Game and Watches. Mr. Game & Watch's Target Test also takes place on a modified version of this stage. Also, two event modes in Super Smash Bros. Melee also appear fighting on this stage.
