Undertale, one of the most iconic indie games of the last decade, is celebrating its tenth anniversary in a way that has left fans more intrigued than ever. During a special anniversary stream organized by Fangamer and the game’s creator, Toby Fox, viewers were surprised by the inclusion of completely new areas and changes that seem to connect Undertale more closely with its spiritual successor, Deltarune.

Among the most notable revelations is a new and grim area filled with ruins, as well as the rare Gaster door, which traditionally appears only in a monochromatic format. In the broadcast, this door was shown in color, which is unusual and has sparked a great deal of speculation among fans. These changes have not gone unnoticed, and fans soon noticed that the ruins seen in the stream also appear in the introduction of Deltarune, generating theories about the enigmatic Gaster’s connection to both works.
The reactions on platforms like Reddit and YouTube reflect the widespread enthusiasm of the community. A comment on YouTube expressed: “Toby really knows how to get people excited,” referring to the details that have sparked fierce debates online. Rumors suggest that this could be a hint towards a future Undertale DLC or an anniversary update, although it seems these elements were created solely for the stream.
However, Toby Fox was clear about the timelines for Deltarune, indicating that Chapter 5 will not be released before the first half of 2026, but emphasized that there are no external factors that compromise this date. With the intrigue surrounding Gaster and his relationship with the new areas, the community remains eager for what will come in the development of Deltarune.
