Every year there will always be an event that is all about Undertale and Deltarune. Well-known AU characters will appear. Fan games, comics, animation and much more announcement. And a mysterious story behind the event.

UNDEREVENT is a huge project that will be a presentation of UNDERTALE and DELTARUNE projects, both large and small. Each project will have their developers, not only give a basic rundown of their projects but will also be showing off teasers and trailers.
