Nintendo announced the release of the Gold Classics Pack today for New Super Mario Bros. 2, which will serve up a banquet of three Coin Rush levels based on classics from Super Mario Bros.and Super Mario Bros. 3.
However, the best bit is that Nintendo are offering the pack for free until the end of next January as a big thank you to everyone's helped collect over 300 billion coins in New Super Mario Bros. 2 thus far.
You can buy the pack from the "Shop" button in the Coin Rush sub-menu. Of course, before that happens, you'll need to activate said button via SpotPass. Confused? Click here for more details.
