Nuclear Throne hosts a variety of music tracks to add either ambience or flair to an area/boss. There are a total of 35 tracks within the original soundtrack, though they are split up into 36 within the game files.

All the music in Nuclear Throne was composed by Jukio Kallio who has repeatedly worked on soundtracks for Vlambeer titles - Luftrausers, Gun Godz and Yeti Hunter as listed on his website.

Any music in-game can easily be replaced on PC versions using the music editing guide.

Each song in game ends abruptly in order to loop smoothly while in the soundtrack it slowly fades out, so the length of tracks between the OST and in-game tracks differ. Some themes only play under specific conditions listed at the bottom of the page.

Alt Themes


B-Themes are alternate themes that can play in place of normal themes. They only play in main areas if a vault is spawned during its second level.

More detailed, this includes the Scrapyards and Frozen City in preloop. In loop this also includes the Desert and Palace areas.
B-Themes have a 5% chance to play when entering those areas, or is guaranteed to play if the player is at 1 HP or below.
Once all three vaults are visited in a run B-Themes no longer have a chance to play as vaults no longer spawn. Because of this, Palace B-Theme is very rare to hear.
As weeklies spawn vaults in their destroyed condition, B-Themes always have a chance to play throughout the entire run.


There are two other alternate themes, the first being "The Place I Once Called Home." This will only play when entering the IDPD HQ during a run as Rogue, a unique track to tie her character to that area giving a more somber feel.

The other rare theme, "Campfire", is an easter egg that will play after the main menu theme finishes on the character selection screen, but only if the Vlambeer logo appears in the campfire. This is a very obscure easter egg and most players will go through the game without knowing about this track because of its obscure conditions.
