2d20 System Reference Document

About this source

The 2d20 System Reference Document (or 2d20 SRD) is a free toolkit that allows creators to craft their own 2d20-based role-playing games and supplements. It explains all the core mechanics of the system, enabling game designers to create exciting experiences around Modiphius’ cinematic high-action and dramatic ruleset. The 2d20 SRD serves as a central reference for the “core” of the 2d20 System, as well as several common genre-specific modifications, to be used both internally by Modiphius writers and designers, and externally by licensees and affiliates. It will also serve as the basis for the community content program - 2d20 Worldbuilders - expected to launch in January 2023. The 2d20 System is a toolset for creating and playing games that emulate and celebrate action-packed, story-driven fiction. It thrives when paired with a setting or theme where competent, determined, often larger-than-life protagonists face tense and perilous situations, and where collaboration and teamwork are vital to success. It aims to pair the action of the story with a degree of mechanical impact, so that what happens in the narration has direct consequences in the game, and vice versa, and relies on players and Gamemaster alike being active participants in both the fiction and the gameplay.
