We shared details on the upcoming Undertale Live concert the other day, but some really interesting info has come out since then. While Undertale Live will give fans a way to hear their favorite songs live, it'll also include an interactive audience element, as well as secrets.
At certain points during the show, the audience will be able to vote on how things should go next. These decisions will lead to the game's three endings, which are neutral (kill some, spare some), pacifist (kill no one), or genocide (kill everyone). These endings will be accompanied by visuals from the game as well.
While this may have some show-goers worried that they won't hear their favorite songs during the performance, those involved with the show have said that there could be some secret elements and actions that allow the audience to jump between timelines and hear certain tracks. It should lead to very varied performances between audiences.
As we originally said, the only location announced for Undertale Live right now is Chicago, but the team putting the show together has confirmed that there will be more dates in May, and a proper North American Summer 2020 tour.
