New Super Mario Bros. 2 - Coin Rush - Nerve-Wrack Pack

The Nerve-Wrack Pack is a downloadable addon for New Super Mario Bros. 2 on the Nintendo 3DS, released in 2012, that extends the core experience by introducing highly difficult Coin Rush courses. This pack requires the base game and focuses purely on platforming mastery, as its stages are rated five-star difficulty and notably lack any Checkpoint Flags, meaning no time bonuses can be earned upon failure. It integrates directly into the existing Coin Rush system, offering expert players a substantial, unforgiving challenge using the main game's mechanics.
