Questions & Answers

When is the game going to be released?

The project started on June 12th, 2025. Since then, we have created countless assets, reviewed every elements, and went through several iterations of our Undertale engine to bring the best, most polished experience to our fanbase; we want to share how much fun we've had making this through the experience we provide.

All of this to say, we are super excited for the release!

While we don't have a date of release planned, overall game progress can be tracked live through this document, where you can find information about the cast list, game areas, and percentages of asset completion. If you really cannot wait, you're also free to sign up for beta-testing, available in our community server.

Between you and me..? Probably around Q1-Q2 2026.

Can I contribute to the project?

The xyroyumi team would love help on promoting our game. We want to build up anticipation for the release & need people to share our project to the world.

Invite fans to our Discord server, write a post, record something... Anything helps, and means a lot more to us than you could ever realize!

+ an additionnal benefit: permanent Content Creator role to claim in our Discord server, exclusive to promoters!

Do you have permission to make this project?

The SCP Wiki hosts its creations under a very-open license: CC-BY-SA 3.0, which favorizes fan content creation. More can be found here.

Alternatively, Undertale's own creator, Toby Fox, has stated terms via email (which we respect) for the creation of fan-made games.

Is fan-art / merch of the game allowed?

We openly approve of and allow fan-art & other fan-content made of Undertale BREACHED, so long as the aforementioned content respects the SCP Wiki's licensing guide and is not locked behind a paywall to respect Toby Fox's Undertale fan content policy.

For merch inquieries, the situation becomes a bit more ambiguous. Refer to this post for guidelines.
