UNDERTALE is an indie RPG created by Toby Fox where nobody has to die! Take control of human, who fell into an underground world filled with monsters. It's up to you to make strange friends or stranger enemies as you FIGHT or ACT through unique RPG/bullet-hell battle system and try to find your way out. Will you show monsters standing in your way MERCY, or slaughter them all?

More UNDERTALE?! Not exactly, but if the game left you craving for more, check out Toby’s next project, Deltarune! The first two chapters are out and you can try them out for free!

The Underground awaits

Welcome to r/Undertale, Reddit’s largest UT community, a place for fans to share fanworks, memes (occasionally not skeleton related), hold discussions and argue about the same three theories ad nauseum. Posts about Deltarune and Alternate Universes of both games are also welcomed!

Subreddit's rules

1) Be relevant to Undertale or Deltarune

Keep your posts on topic! Posts discussing/sharing content about Undertale AUs, Deltarune AUs, or the subreddit itself are also permitted. If the connection to UT/DR is too tenuous, the post may be removed under this rule as well.

2) No sexual or otherwise obscene content

Do not share or discuss content that is more sexually suggestive or obscene than the game itself.

3) No bootleg merchandise and pirated content

Don't promote the kinds of merchandise that Toby is not okay with. Details here
Discussions of piracy and attempts of illegal distribution of the game are not allowed. Additionally, since there is no official port of Undertale to mobile devices, most of the available ones count as piracy too. As such do not discuss or share screenshots of these versions here.

4) No soliciting

Do not ask users to participate in anything that is not Undertale-based.
Do not pit us against outsiders.
Do not post about upvotes.
Unless you are looking for help with fan project related to Undertale, please don't make posts that are just invitation to subreddit or discord
Low effort linking to streams, or let’s plays is not allowed unless the stream is of special occasion (charity, some event…), or if the video is of higher production value

5) Sharing art and fanworks

While sharing any form of fan work, tag your post with appropriate flair, distinguishing it as either Original, or Found creation (or My / Found meme art).
If the creation isn’t yours, you are REQUIRED to provide a link to the original.
Art used in other post types SHOULD be properly credited as well.
Redraws, covers etc. may be tagged as OC, provided you link to the original in comments and name the artist in the post’s title.
Full version of the rule + how to track down art sources can be found here

6) Etiquette

Remember the human on the other side of the screen and treat them with respect.
Don’t post memes about sensitive or otherwise inappropriate subjects (such as suicide, serious ongoing issues etc.)
Slurs, brigading and bigotry of any kind won’t be tolerated regardless of context.
Posts and comments must be in English so they can be properly moderated.

7) Avoid reposts

Posts identical or nearly identical to recent submissions (recent being 6 months) will be removed as reposts.
Exceptions to the 6-month rule are top / most-frequently rehashed posts and reposts of content you have already submitted before.

8) Content Quality

Mods reserve the right to remove your post if;

It has been made quickly with little to no effort on display
It falls under repetitive content the subreddit has collectively decided to start removing
It’s asking a question answered in FAQ wiki page
Its topic has historically proven to yield nothing but toxic discussions

Common examples we tend to limit our removals to can be found here

You can modmail us with any concerns.
