- 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.

- soliciting, please.
- Do not ask users to participate in anything that is not Undertale-based. * Do not pit us against outsiders. * Do not post about upvotes. * 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 * 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
- Sharing fan work: 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.
- 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.

- Exceptions to the 6-month rule are top / most-frequently rehashed posts and reposts of content you have already submitted before.
- 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 has been made with genAI
- It’s asking a question answered in FAQ wiki page
