It’s important for you to know how the Atomic RPG system works for you.

Universal Core Rules

A set of RPG rules that govern all actions for every player. No exceptions for the Game Master, or a player playing a certain character or someone that has a book you do not have.

It's a d20 system meaning it uses a 20 sided dice to determine success or failures.

Truly Play Anything

The Atomic RPG System allows both players and game masters to create whatever they want. Any genre. Any lore. Any fandom. Anything.

Roleplaying and story telling are not bound to the rules. This means you can let your imagination run free and not worry about game penalties or bonuses. True story telling freedom.

Gaming Freedom

Combine these first two pieces with the online digital tools and your gaming freedom is unleashed.

Play anywhere there is internet. Use easy to learn balanced rules to govern your game. Then tell your story however you want.

Create your own completely custom content!

Or use any of the custom content created and submitted by other Atomic RPG system gamers just like you!

What do players and game masters have to say about the Atomic RPG?

"This game was super easy to learn and fun to run. It worked great for my super hero campaign. The players loved that they could come up with the craziest fun descriptions for their super powers and still have balanced fun battles."
Ryan J
Game Master
"I love playing the Atomic RPG System. I can play our D&D style fantasy game on Friday with my friends. During the weekend I can play the game my kid is running where we are all cats. Then if I get a wild hair we can play some Supernatural monster hunting one shots!"
Valerie W
Player and Mom of GMs
"Not only can I run any genre I want, I can run any type of game I want with the Atomic RPG System. I ran an awesome Steampunk style campaign where some nights we just did roleplay. Other nights it was just skills. Then of course battle royals. Whatever I wanted, it provided."
Bill T
GM and PC
