Super Mario USA follows Mario, Luigi, Toad, and Princess Peach as they journey into the dream world of Subcon to save its people from Wart, a toad king who has taken control of the land.
The game adds a central lift-and-throw system, letting characters pull vegetables from the ground or pick up enemies and hurl them as weapons. Players can choose from four distinct characters, each with different running speeds and jumping abilities.
Super Mario USA is made up of seven worlds, and each world is split into three stages before ending in boss fights that depend on careful item use. Players move through both the surface and sub-space areas, with magical potions opening hidden spots filled with coins and power-ups.
First released in Japan as Yume Kōjō: Doki Doki Panic, Super Mario USA presents a separate visual style and gameplay structure that sets it apart from the standard Super Mario Bros. formula.
