CATS (Crunchy Automated Tactical System)

Every hit lands somewhere.

CATS is a detailed, tactical tabletop RPG. Fights are dangerous, decisions count, and a planned companion app will handle the bookkeeping so the crunch stays fun.

How it plays

Tactical depth, less table friction.

CATS is for players and game masters who like detail in a fight: where the blow lands, what your armor stops, and what it costs you afterward.

01

Hit locations

A hit lands somewhere specific, and each location takes its own damage. A wounded arm is a different problem than a wounded leg.

02

Percentile skills

Skills run on a d100, and your skill is your chance: 70 means you succeed on 70 or under, before the situation shifts it.

03

Gear that matters

What you carry and what you wear changes the fight. Choices before the battle count as much as choices during it.

The companion app

Let the app carry the numbers.

Track

Bookkeeping handled

A companion app for phone and PC is planned to track the crunch for you, so the session goes to playing instead of math.

Designed to grow

CATS is built to span settings, from swords to starships. Settings and worldbuilding are in development for each major setting. See where each one stands.

Our symbol

Every setting, one orange core.

In RoundHelix Games, orange is the CATS rule system and each game setting brings its own color, every setting connected to the others through the same orange core.

The helix wrapping the two is collaboration between rules and setting, and the circle around them is continuous improvement.
