We’ve finally released the first DLC pack for Trombone Champ: Unflattened, the UNDERTALE + DELTARUNE Song Pack, available now for $7.99 USD. Bring your best intonation. Or don’t. Some people insist it’s all about intent anyway.
A parallel timeline just leaked into the Trombiverse, bringing heartfelt anthems, reality‑warping boss themes, and a salesman you probably shouldn’t trust, all on brass. Veterans may feel a sudden surge of… resolve. Newcomers may discover that, no, you actually can’t dodge everything forever.
Six Tracks Enter. Your Lung Capacity Leaves.
From UNDERTALE
Megalovania - Short rests. Long judgments. One very patient skeleton. Try not to have… you know… that kind of time.
Hopes and Dreams ~ SAVE the World - For when the soundtrack stacks every motif you’ve ever cared about and asks if you’ve still got the determination to keep sliding.
Battle Against a True Hero - Spears flying, BPM spiking, and zero room for mercy. You know exactly who this is for.
From DELTARUNE
BIG SHOT - Take the deal. Become a real (tromboner). Don’t click the blue hyperlinks.
Black Knife - Frost in the air, questions you definitely didn’t ask, and a route you swear you’re not on.
The World Revolving - CHA… (ahem) a certain jester insists you can do anything. Your intonation strongly disagrees.
Each track has been mapped for VR trombone performance, complete with reactive environments, bespoke slide patterns, and the exact amount of chaos necessary to make you question every decision that led you here. Improv, Campaign, Freeplay: play them your way, SPARE nothing, and try not to get judged. By yourself... or anyone wearing a hoodie.
Slide back into the Trombiverse with six of indie gaming’s most beloved tracks, now filtered through the most dignified instrument ever conceived. (No, really. Stop laughing.)
