This SDK (System Development Kit) serves as a collection of guidelines, advice, and tools to make custom content (MODS) for the GUTGUN solo RPG— or making your own FULL OF GUTS (FoG) games. 

GUTGUN is a solo TTRPG (table-top role-playing game) that translates the blood-pumping fun of a classic PC shooter to tabletop.

You can find the free SRD, which contains GUTGUN's core rules, on this page— and the full game can be bought here.

CONTENT WARNING for the GUTGUN SRD: The GUTGUN SRD contains some out-of-context blood, meaning that there are some stylized illustrations with nameless red liquid.

MODDING

Want to make your own CAMPAIGNS, ENCOUNTERS, GUNS, ENEMIES, CHEAT CODES, or other supplemental content for GUTGUN? Want to make an entirely new TTRPG that’s based on GUTGUN’S mechanics? 

You’re free to do so! Please stick to text from this SRD (try to write things in your own words if you can!), and include the following text somewhere in your work: 

This PRODUCT is FULL OF GUTS, based on or inspired by the GUTGUN TTRPG by GRACE GITTEL LEWIS. This PRODUCT is not directly affiliated with GRACE GITTEL LEWIS in ANY WAY.

You may also use the FULL OF GUTS logo below, which you are free to pop somewhere on the cover, inside the credits, in a margin— wherever you like! You can find the logo free to download below.

If you make something with these tools, I wanna see!

And, finally, if you like what you see here, please consider buying the full game!
