Earlier this morning, the official Undertale Twitter account tweeted a bunch of mysterious tweets and made their profile picture black.

A new development has surfaced – the account has told followers that they have something to show everyone, and it will be done in 24 hours. Whatever they’re planning to reveal (could be Undertale 2, could be something related to Halloween) will be announced on October 31, 2018 8am EST / 5am PST.

RETURN HERE IN [24] HOURS.
