TETRIS 99 - Big Block DLC (Nintendo Switch)

The Tetris 99: Big Block DLC is a feature expansion for the base puzzle game, requiring the core software to play. Released in 2019, this content shifts focus from the online battle royale to offline and local play, introducing four distinct modes: CPU Battle (offline 99-player simulation), Marathon (high-score challenge), 2P Share Battle (local two-player versus on one console), and Local Arena (up to eight players via local wireless). It enhances replayability by providing structured environments for the established block-dropping mechanics without adding new core gameplay systems.
