Wrecking Crew '98 is an action puzzle game released exclusively in Japan in 1998 for the Super Famicom's Nintendo Power download game service and later for the Super Famicom itself. The game is a sequel to the original, which is included as a bonus in the game. Unlike the original, in which the player's objective was to find ways to clear each level of all panels, Wrecking Crew '98 takes a more competitive approach, where two opponents are given their own sides to clean up. Each player must try to demolish as many panels as they can on their side, until the opponent's side is completely piled up, to win.
The game's story mode features Mario returning to the Mushroom Kingdom from a trip, then discovering that Bowser has started a construction campaign of building new hideouts. The construction is depriving the flora of sunlight and thus, Mario decides to demolish the new construction sites with his hammer. Along the way, he meets his old enemies from the original Wrecking Crew, including former rival Foreman Spike.
