The first two levels from the classic NES game Super Mario Bros. has been reproduced, hacked, and parodied online too many times to count.  

Last year, BlueMasters studios went viral with their extremely impressive 2D-3D hybrid parody of World 1-1, titled Super Modern Mario Bros., garnering over 1.5 million hits

Now, they have finally returned to continue the modern reproduction of the classic game with this video of theoretical “game play” from the familiar World 1-2 underground level
