Dropzone is a European-exclusive NES game developed by Eurocom and published by Mindscape. The game plays identical to Defender, in that you must shoot all the enemies on screen, and there's a map of the level on the bottom of the screen.

The game has a disappointing soundtrack because even though the game was made in 1992, the game contains only a single track which plays as soon as the player turns on the game. It was composed by Neil Baldwin who came up with the song by playing with the NES' arpeggio features. The song is in the 6/8 time signature. To create the game's music and sound, Neil wrote the music in 6502 assembly, using his own sound driver.
The NSF file also contains an NTSC version of the song. However, because the game was only released in Europe, only the PAL version will be uploaded on this site.

It is unknown why the game lacks credits, especially for such a late release. Neil has discussed the music on his website dutycyclegenerator.com.
This rip is missing songs.
Ripping NES music is an arduous process that is beyond the scope of this site. The music was recorded in NSFPlay.
