New Super Mario Bros. 5: Clone Tag Team - Release Trailer (Hack)

This title, New Super Mario Bros. 5: Clone Tag Team, is a 2012 ROM hack/mod for the Nintendo DS platformer, building upon the original's 2D side-scrolling mechanics. As a modification, its core value is delivering entirely new, community-created level designs and challenges layered onto the familiar Mario engine. Its distinctive feature, suggested by the title, centers on a "Clone Tag Team" mechanic, likely requiring players to manage or alternate control between multiple character entities to solve platforming puzzles or overcome obstacles.
