INSTRUCTIONS

Requires USTMananger (

  • Drop into plugins or UST folder / just use r2modman or something
  • Go to Settings > Audio > Open UST Manager > select the thingy
  • Current File Size: 130 MB

Some sounds / music also need an additional setting in USTManager turned on to work called UpdateBasedSwappingEnabled

WARNING. Turning on the option has some side-effects. From my testing: it has issues with sliding sound effects, Freezeframe ticking and probably a bunch of other stuff.

If you have Configgy installed. It can be done in-game.

Manual Users. Go to BepInEx/config/dev.zeddevstuff.ustmanager.cfg, open it up with a text editor and put in true.

r2modman Users. Go to ConfigEditor, find the same up above, edit config and- you're a smart cookie, figure it out

WHAT IS THIS

Another UST mod clogging up the website oh wait soundpacks have their unique section now haha

A WIP music replacement pack containing my own covers on the Ultrakill soundtrack. Yes. By me. An idiot.

What's included (so far anyway)

  • The tracks below include youtube links if you wanna give a quick listen and see how crappy the covers are.
  • Total Tracks: 29

Misc [idfk ( - BONUS PACKS - ) ]

Included with Main Mod | Terminal Music / Take Care

(Take Your Time [ft. Teto & Rei])

Contains non-canon singing:)

Doesn't replace all instances. (ehem prime terminals)

Either I did it wrong or USTManager doesn't like them.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
