2d20 System Reference Document
 |
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.
