Snow Field plays in the snowy stage in the Contra games. The song was composed by Kazuki Muraoka. The title is unofficial.
The final stage of the arcade version of Contra has four sections. The first section, the snowy field, is where you'll hear the Snow Field tune.
In the NES port, Snow Field is played in stage 5.
The background animation is much better in the Japanese version, the song remains the same throughout every region and the PlayChoice-10 release.
