Atomic Runner Chelnov is a Japanese runner arcade game developed and published by Data East in 1988.
A port to the Sega Saturn was planned and developed, but was never released to consumers. A version of it appeared in the Tokyo Game Show and several game stores in Akihabara around 1997, but its release was cancelled by Data East for unknown reasons. A fully playable prototype of the Sega Saturn version was found in 2012. The Saturn prototype is a duplicate of the 1988 arcade game but lacks sound effects, though the music is still present.
In 2021 Obscure Gamers obtained the original disc found in 2012 and in 2022 it was given to VGPM.
