Some Undertale teasing is happening on the Internet this morning. The official Twitter accounts for both the game and Toby Fox, its creator, have been sending out cryptic messages revealing an October 31, 2018 announcement.

It all began on Fox’s account, where a message suggested “someone” wanted to talk to us.

It’s cold. It’s as if everything had been enveloped in a black wind… You didn’t realize it yet, but… it seems that there’s someone who wants to talk to you. — tobyfox (@tobyfox) October 30, 2018

About an hour after Fox’s message, the official Undertale account began sending out teasing messages. It began with a “WELCOME.” Following that, there were brief notes that led to the following message when put together. (Remember, Papyrus always speaks in all-caps in Undertale.)

WELCOME. HAVE YOU BEEN LOOKING FOR ME? HOW WONDERFUL. I HAVE BEEN LOOKING FOR YOU AS WELL. I HAVE SOMETHING SOMETHING I WANT TO SHOW YOU SOMETHING I THINK YOU WILL FIND VERY, VERY, INTERESTING BUT IT IS NOT COMPLETE YET NO IT IS FAR FROM COMPLETE THUS I HAVE A SMALL FAVOUR TO ASK OF YOU. RETURN HERE IN [24] HOURS. AT THAT TIME, I WILL ASK YOU A FEW QUESTIONS. THEN USING YOUR RESPONSES WE WILL APPROACH ITS REALIZATION. THANK YOU VERY MUCH FOR YOUR TIME. I WILL BE IN CONTACT AGAIN SOON.

These messages were following by another tweet from Fox noting that whatever this project is, it will require a PC.

For those who completed UNDERTALE it’s really important that you check @UNDERTALE 24 hours from now. I want to make something new, and it all begins with your feedback. A Windows PC / MacOSX PC is needed. https://t.co/N1IJLyiswy — tobyfox (@tobyfox) October 30, 2018

Undertale is available for the Nintendo Switch, PlayStation 4, PlayStation Vita, and PC. As a reminder, an Undertale Alarm Clock app was announced in 2017 and has a tentative 2018 release window.
