In spite of everything, Undertale is now celebrating its 10th anniversary. To mark this significant milestone, a special one-night orchestral event titled The Determination Symphony has been announced. Those interested in acquiring tickets for this unique event—set to take place at London’s Eventim Apollo on June 22, 2025—can do so beginning tomorrow, March 28, at 6 AM ET.
According to the event’s press release, the concert will run for around two hours and will feature a journey through Undertale’s decade-long story, beginning with “the initial fall at Mount Ebott and guiding them through Froggit Village, the Snowdin Temple, Temmie Village, and much more.” Accompanying this journey will be a 25-piece orchestra performing original music by developer Toby Fox, which has received continuous acclaim and recognition over the years. This appreciation includes that highlighted in GameSpot’s Undertale review, where we noted, “Undertale’s soundtrack possesses a timeless charm and excels at evoking emotions.”
Lambert Jackson Productions, the London-based studio behind the Oliver award-nominated show Cruise, is set to lead the production of The Determination Symphony. The event is slated to occur at the Eventim Apollo (formerly known as the Hammersmith Apollo), one of London’s top theaters.
In other Undertale news, the game recently set a new Steam record for concurrent players. After pricing the game at $1 during the Steam Spring Sale, developer Toby Fox took to X to share the news.
