The full soundtracks are available for purchase on their Bandcamp page, with streaming platform versions omitting tracks not composed or performed by them.
The three tracks contributed by Meganeko, KEYGEN CHURCH, and HEALTH are available on their respective pages. Additionally, the tracks used in the Developer Museum are credited under Hakita's own name.

HEAVEN PIERCE HER - ULTRAKILL: INFINITE HYPERDEATH
Released on Bandcamp and YouTube September 11, 2020.
Song Information Audio
INFINITE HYPERDEATH.jpg

01 - The Fire Is Gone (for Piano, Saxophone and Trumpet)
FOR THE MAIN MENU
& THE BOOT-UP SEQUENCE
COMPOSED BY HAKITA
  • This song originates from the end of "The Fire Is Gone, and I Remember It Best: The Closing" by redherring, another musical alias of Hakita's. Though the clip is the finale of its original album, it instead is the opener for ULTRAKILL's soundtrack.
  • Originally used only for the intro, to contrast the chaos of the game with a slow, delicate start. It was then reused for the main menu as a placeholder in a later demo version, though it ended up fitting well enough that Hakita decided to keep it.
  • Has additional, themed variants for each seasonal event in game:
    • Christmas (Piano and Bells)
    • Easter (Piano and Harpsichord)
    • Halloween (Organ and Xylophone)

02 - Into the Fire
FOR 0-1: INTO THE FIRE
& 0-3: DOUBLE DOWN
COMPOSED BY HAKITA
  • A quiet drone plays during the tutorial.
  • Another drone plays in the tight hallways at the start of 0-1, getting louder and playing over itself before cutting out as the player approaches the revolver.
  • A guitar hit then plays once the revolver is picked up, before transitioning into the combat loop.
  • The second drone and guitar hit sample a chord from "Mars, the Bringer of War" from Gustav Holst's Planets Suite.
  • The slow-paced, bass-heavy segment in the soundtrack release originates from early experiments where the music adapted to the currently equipped weapon, which was scrapped due to interrupting tempo and combat intensity. (Original Bass Version)

03 - Unstoppable Force
FOR 0-2: THE MEATGRINDER
& 0-4: A ONE-MACHINE ARMY
COMPOSED BY HAKITA
  • An early version of this track's calm loop plays in the soundtrack version's intro. The full loop can be listened to here, and its unused combat loop counterpart can be listened to here.
  • Though one of the riffs is often compared to "At Doom's Gate" from the Doom soundtrack, the similarity is purely coincidental.

04 - Cerberus
FOR 0-5: CERBERUS
COMPOSED BY HAKITA
  • First part plays until entering the Cerberus Arena; progresses once Cerberus Cerberus awakens.
  • Cerberus is the very first song Hakita composed for ULTRAKILL.
  • It can be heard in Hakita's very first dev video on ULTRAKILL.
  • The intro is the main part of the song, slowed and pitched down. In-game it plays at 33% speed, but for the soundtrack release it plays at half-speed due to sounding better in isolation.

EDITED BY HAKITA

    • The New Blood splash animation
    • Most Terminals
    • The Cyber Grind results screen
    • "Thanks For Playing" development endscreen
  • The song is entirely sampled from the song "Were You Foolin'" by the Russ Morgan Orchestra.
  • The aged sound of the track is a reference to "Everywhere at the End of Time" by The Caretaker, a music project that explores memory and its deterioration.
    • The music's title further reinforces the reference with the aforementioned album's author, Leyland James Kirby, better known under his pseudonym, "The Caretaker".
  • The first loop (sampled from 0:08 to 0:37) is used by all yellow Shop Terminals, while the second loop (sampled from 2:05 to 2:34) is used by the blue Cyber Grind Terminal and in the Cyber Grind results screen, as well as the "Thanks For Playing" Early Access endscreen that appears when the player reaches the end of the currently-released campaign levels.
  • The version of "Take Care" that plays in the Cyber Grind Jukebox loops the first (0:08 to 1:06) and second (2:05 to 3:03) instrumental sections three times before finally playing one loop of the vocal segment (1:06 to 2:05). This makes this version the only one to contain vocals.
