Nicalis and NIS America are giving Cave Story a full remake for the Nintendo 3DS. This version of Cave Story is still a platformer, but the game uses 3D models instead of sprites. I played a tiny bit of it and it was just like Cave Story 2.5D.
When NIS America announced Cave Story 3D, they said the title was on track to be a "launch window" game. We honed in on the date and Cave Story 3D is scheduled to be in stores on June 28.
In addition to 3D graphics, producer Tyrone Rodriguez and creator Daisuke Amaya mentioned to Siliconera in an interview there will be new elements in this version of Cave Story. Amaya pointed out new and old music and Rodriguez said there would be elements from the unreleased Cave Story beta.
