Undertale sequel Deltarune’s new chapter gets a surprise September 17th release - The Verge

The news came on September 15th during a livestream of Deltarune Chapter 1 put on to commemorate Undertale’s sixth anniversary.

Hosted by three dads from Fangamer — a gaming merchandise retailer — the Deltarune livestream featured hideous dad-approved shirts, canned laughter typical of a ‘90s sitcom, and commentary from Toby Fox himself via a skateboarding Annoying Dog proxy with a text-to-speech voice.

You can (and should) check out a VOD of the wholesome stream here.
