Undertale update seems to include some sort of secret new content

Undertale creator Toby Fox said back in November that it was unlikely that any forthcoming patch “will contain anything other than bugfixes.” And that appeared to be the case with the update that was released on Steam yesterday, which promises to “fix bugs and increase compatibility,” but nothing more. Nonetheless, the sharp-eyed members of the Undertale subreddit have determined that there may be more going on than meets the eye.

“Determined” might be putting it a little strongly, but they certainly seem to have a plausible theory. To make sense of it, if you're not an Undertale veteran, you'll probably want to have a look at Kotaku's summary, which contains some big but necessary spoilers. Essentially—and this will be a spoiler too, so consider yourself warned and look away now if you don't want it blow the surprise, because this is your last chance!—the new content, which includes new dialog and a changed audio file, appears to add the pseudo-mythical character known as Gaster to the game—sort of, anyway.

Interestingly, Fox seemed to hint at something being hidden away in the update (even as he denied the existence of new content) through a series of tweets he posted yesterday, in which he subtly encouraged players to poke around under the hood. "BTW, just want to clarify, the lack of new content is in no way due to people datamining the game. No hard feelings towards those people," he wrote. "The only reason I tried to get people not to datamine is so fans could experience things before they were found in the code... Anyway, I have no problem with that kind of stuff now. After all, game hacking leads to things like fan translations, which are great."
