Play Gunk's arena as V1, the ULTRAKILL machine.
- V1's movement in Gunk: run fast, dash (Shift, 3 stamina bars), slide (Ctrl on the ground, jump out of it to keep the speed) and ground slam (Ctrl in the air: the shockwave hits every Gunk around you).
- Revolver and shotgun replace the rock throw (1/2 or mouse wheel to swap, left click to fire), with ULTRAKILL's own gun sounds. Gunk's upgrade cards still count: Rock Damage, Throw Speed and the crit upgrades power V1's guns, and Gunk's Explosive Rocks power-up makes every shot explode.
- ULTRAKILL's style meter, D to ULTRAKILL rank with the original rank art: kills, airshots, crits, multikills, ground-slam kills and quickdraws after a dash.
- ULTRAKILL's music: 1-1 in the story arena, 4-2 in endless, and 3-1 "Guts" when the boss Gunk shows up.
- Gunk's own waves, flying Gunk, XP, upgrade cards, power-ups, boss and endless mode, unchanged.
Solo. You need both games: everything from ULTRAKILL (sounds, music, rank art) is read from your own copy of ULTRAKILL while you play, nothing is copied.
Built with BepInEx 5 (bundled, LGPL-2.1) and Harmony.
