Siegebreaker Game Studios
Tabletop RPG worlds built for consequence.
We publish games and adventures where strange worlds, dangerous missions, unusual powers, and player decisions shape what happens next.
Published game lines
Gateways into Madness
Exploration, intrigue, tactical danger, and Mythos horror across worlds reached through ancient gateways.
Shattered Worlds
Post-apocalyptic science fantasy where technology, magic, survival, and professional teams collide.
Tactical choices. Human consequences. Campaigns with memory.
Our work connects characters, equipment, powers, missions, and long-term consequences while keeping the people undertaking those missions at the center of play.
Publishing and collaboration
We welcome conversations with writers, publishers, and rights holders about tabletop adaptations, adventure development, and game-system collaboration.
