Music and radio

Undermine Squad has a built-in radio with eleven stations and almost 100 tracks. All tracks are under free licenses (CC0, CC BY, CC BY-SA). You see title, artist and license while a track plays, and in the menu under Credits.

The game remembers your favourite station and your volumes.

Controls

• M: next track
• Shift+M: next station
• Note icon in the HUD (top right, next to the menu): opens the radio with stations, previous, pause, next and the sliders
• Gamepad: tap Back for the next track, hold it for the next station
• Phone and tablet: tap the note icon

When the music changes it crossfades, and Now playing shows title, artist and license for a moment at the bottom centre. You can turn the popup off in the radio.

Volume

The radio and the Settings have three sliders:

• Music: the radio
• Effects: digging, blasting, tools, menus
• Ambience: wind, fire, water, animals and elevators

The Music on/off switch in the settings turns the radio off completely.

Adaptive music

With Adaptive on (the default), the music reacts to the game:

• Above ground the music stays calm.
• Underground the music sounds muffled. On the Auto station the radio switches to Underground.
• In combat (enemies or monsters nearby, attacks, sieges) Auto switches to Metal or Epic, whichever you picked with Combat: Metal or Combat: Epic. After about 20 seconds of calm it switches back.
• On victory a short fanfare plays.

Note

With Combat always the combat layer also switches when you picked a fixed station.

Tracks load only when they play. That keeps the game small, and each track comes only when it is needed.
