Description

Six Legendary Tracks. One Unstable Trombone. The UNDERTALE + DELTARUNE Song Pack brings a whole new level of chaos (and possibly spiritual awakening) to your trombone.

Toots of Determination

Six Legendary Tracks. One Unstable Trombone.

The dog has done it again.

UNDERTALE and DELTARUNE are now officially part of the world’s most off-key rhythm game. That’s right! Your slide-to-glory journey now includes the ability to absolutely obliterate clergy with an edgy, modern take on Megalovania. Or take the pacifist route and hold onto your HOPES and DREAMS while aiming for the highest Champ Streak. No matter how you play, the most important journey is the one you take with family and friends.   

This paid DLC invites players to toot, honk, and glissando their way through six legendary bangers from two of the most beloved RPGs of all time. The UNDERTALE + DELTARUNE Song Pack brings a whole new level of chaos (and possibly spiritual awakening) to your trombone.

🎵 Songs from UNDERTALE:

  • Hopes and Dreams ~ SAVE the World – now with 100% more vibrato.

  • Battle Against a True Hero – your trombone is not ready.

  • Megalovania – this is the sound of judgment.

🎶 Songs from DELTARUNE:

  • BIG SHOT – you know what time it is.

  • Black Knife – edgy. moody. trombone.

  • The World Revolving – now revolving in a circle of regret.
