Atomic Runner Chelnov is an unreleased title for the Sega Saturn which was mostly completed but never distributed. Data East was set as the publisher and it was displayed publicly at the 1997 Tokyo Games Show, along with multiple game shops in Akihabara, Tokyo. Despite this, Data East canceled distribution without notice or reason. We assume that the public play testing produced unsatisfactory interest which prompted Data East to cancel the project.

The game ROM was leaked in recent years but is unavailable on most ROM archives. The game displays technical boot data when loading, but otherwise appears to play normally and is an arcade-perfect port of the original title.
