New Super Mario Bros. 2 owners can enter the Coin Rush Shop starting today (and until Jan. 31, 2013) to download the Gold Classics Pack for free. Gold Classics Pack features remixed levels from classic Mario games such as Super Mario Bros. and Super Mario Bros. 3.
I say remixed because Nintendo has inserted multiple secret routes and warp pipes that lead to interesting locations, including more Super Mario Bros. and Super Mario Bros. 3 levels.
If you haven’t reached the 1,000,000 coin mark yet, or haven’t had enough of Level 1-1, you can jump on and download these levels today. Make sure to get the Gold Classics Pack soon though, it will only be available for free for a limited time. The Gold Classics Pack will still be available, but will cost $2.50 starting February 1, 2013.
