Fallen Down (An Undertale/Deltarune TTRPG System)
A downloadable tabletop game
What is Fallen Down?
Fallen Down is a fan made Tabletop RPG (TTRPG) system for Undertale/Deltarune. It is currently unfinished, but I intend to update it as time goes on. Feel free to use it as a base for a campaign if you'd like! This is my first TTRPG and as it stands it's fairly light on rules and content. I'm super nervous to publish this but any commentary/criticism is appreciated!
Brief History
My original attempt at an Undertale/Deltarune TTRPG was called "Kids in Caves" and it was based off of Kids On Bikes. After doing a bit of testing I dropped that system entirely, it was horrifically unbalanced, players all wanted to do different things and take different routes, it was a mess. A few years later I tried again and mocked up an original version of "Fallen Down" and did a one shot with a couple of friends to some generally positive reception. The little intro section with Flowey is a reference to a former version of the document that only my friends have seen, so it is a bit of an inside joke.
Known Issues
There are a few known issues:
- The PDF may display incorrectly on Microsoft Edge as it is in Letter format.
- The introduction says this version will contain a list of items, I did not add them yet as I am focused on other projects for the most part. I just wanted to release what I had for now.
- The artist for an image I have in there may be changing tags, so I'll make sure I update it soon if she does!
- There is some blank space left to fill with nice images and such! I will do this later.
- There is not (currently) a printer friendly version of this, I will make one as this system nears completion.
What's Next?
Version 0.3 will add:
- Basic enemy stats and tips for building encounters
- A section on "ultra bosses".
- An index of items (I wanted to do that this version but I didn't, sorry!)
- Character Sheet (spreadsheet AND form fill-able)
- A setting guide for Undertale and Deltarune
In the future I plan to add:
- A full module based off of Undertale
- A full module based off of Deltarune
- A "quick start" adventure
- An index of example abilities for humans to choose from and reflavor
- A method for building spells for monsters (though I still heavily encourage homebrew)
- (Ideally) a playable module for FoundryVTT
