UNDERTALE Concert Tickets

UNDERTALE: The Determination Symphony gives Toby Fox's beloved soundtrack the full concert treatment: a live 25-piece orchestra performs newly arranged versions of the game's score, curated by Fox himself, synchronized to gameplay footage, and its one Las Vegas date is Saturday, October 10, 2026, at 8 p.m. (doors 7) at Resorts World Theatre. For a game whose music carries half its emotional weight, hearing "Megalovania," "Hopes and Dreams," and "His Theme" with real strings is precisely the point.

Know the format: it's a seated orchestral concert with screens, without interactivity or costumed characters, and its deepest beats land for people who know why a particular leitmotif returning matters. Tickets start at $77 including fees as of September 5, 2026, the exact runtime isn't published, and one weekend night is the entire Vegas engagement. Resorts World sits on the far north Strip, and the fanbase skews young, which makes the venue's age rules worth knowing: children 3 and up need a full-price ticket, and anyone under 18 needs an adult with them.
