A TTRPG set in a star cluster where a small confederation is resisting the pressures of great powers each seeking their own needs, URCAT is the Search and Rescue Arm of a cooperate defense and interstellar security force in the confederation.

Who do I play?

Each Unaligned Rescue and Casualty Assistance Team (URCAT) is run by AI Officers that have access to advanced biomechs called Rescue-frames. These allow them to access special powers and act as advanced combat medics to help those harmed in conflict or disasters in the Twol Confederation. Each Officer serves under the following oath:

I raise arms in defense of those who cannot.

I help the wounded, no matter their homeland.

Civilians out first, wounded next. Only I remain to the last.

I respect the Polities, for their laws are sovereign.

I am not alone, nor are my Officers.

-URCAT Operating Protocols

URCAT rescue-frames can take any number of humanoid and non-humanoid forms!

How does it work?

Illuminated by the LUMEN system, URCAT is built on this fast-paced system inspired by video game-style combat. Actions are decided by simple d6 dice pools based on the approach the character is taking rather than any physical traits or individual skills they may have.

However, URCAT builds on this with card-based medical mechanics inspired by the Surgery mechanics from MASHED: A Korean War MASH RPG to introduce mechanically-powered triage and field medicine. Much of the game's difficulty is  juggling the resources and time need to treat all the patients and evacuate them. If you would like more information on the Triage system, please see my blog post about it here!

Note about Itchfunding:

Please note that URCAT is still considered a work in progress. The current document has no art and only limited layout work. I also intend on refining the game and providing additional entries for the "Equipment" and "Allies and Opposition" Sections. Once I had added more to those sections, I will start to work on finalizing layout,  adding art of my own creation, and creating a character sheet.

However, the itchfunding is to improve the art beyond my own basics. Also, if we hit the goal listed here, I will start working on an stand-alone expansion (or Expandalone, if you will) for URCAT focusing on the Space Naval Combat and boarding actions of the Unaligned Civilian Defense Group! All purchasers of URCAT will get that title for a significant discount upon release!
