Undertale fans received a special surprise on Halloween: the release of a new game by Toby Fox, entitled Deltarune. The first chapter of the game serves as a follow-up to the 2015 hit indie RPG.

Fans were ecstatic when the official account for Undertale tweeted a series of cryptic messages on Oct. 30. They flooded the account’s mentions with several theories.

Like Toby Fox’s preceding work, Deltarune messes with the boundaries between its world and ours. When you install the game, titled “Survey_Program,” you’ll get an ominous license agreement that says “YOU ACCEPT EVERYTHING THAT WILL HAPPEN FROM NOW ON.” Instead of playing as Frisk, you play as a young child named Kris. Familiar fan favorites, such as Toriel, also make an appearance in the game. This is interesting, considering Fox later said in a statement posted on TwitLonger,Deltarune’s world is a different one. With different characters, that have lived different lives.”

In fact, Fox asked that players do not think of Deltarune as a sequel to Undertale at all.

“I will say that basically, what you’re seeing here is not the world of Undertale.
Undertale’s world and ending are the same as however you left them,” Fox states. “So, please don’t worry about those characters, and that world. It will remain untouched.”

Reaction to the game so far is pretty positive, and as expected, the fans have flooded the internet with glorious memes, screenshots, and fan art.

Rather than releasing the game as a whole, Fox explains that he plans to release Deltarune in a series of chapters, explaining that players will “…buy all of the chapters at once as one purchase. That’ll be the only option.” And as for a Kickstarter? Fox said that’s a no. The development of future installations of Deltarune is uncertain, as Fox envisions this project being a more massive endeavor than his last. In fact, he wants to make a team to help him build it.

“Because I really want to make this,” Fox explained. “But I may not be able to succeed because I have no experience successfully directing a team, and I have no idea who I’m going to work with.”

While the future of Deltarune is uncertain, you can at least enjoy what’s available now. You can download the first chapter of Deltarune for free here. You can also grab a copy of the original soundtrack on Bandcamp.
