WiiWare and DSiWare project Cave Story is being upgraded as a full retail release for Nintendo's upcoming 3DS console.
Instead of a straightforward port with 3D output tagged on, NIS America and Daisuke “Pixel” Amaya will be remaking the entire game as a side-scrolling 3D platformer, trying to keep the feel of the original retro project but injecting a lot more polygons.

Remixed music, bonus easter eggs and content will be introduced to add longetivity and for fans, but will remain as close as possible to the original - even down to the level design, enemies and environments, all modelled in 3D.
