Living in Syn
This supplement expands the Crystal Heart roleplaying game with additional character creation options, powerful roles, and training montage tables for developing unusual backstories. It introduces alternative rules for using Crystals, including a variant requiring Agents to synchronize with their Crystal before accessing its full power. New approaches to Requisition include abstract Supplies levels, special services, and consumable power-ups. Guidance for Game Masters focuses on groups operating within a larger organization, alongside additional Savage Tales, eight ready-to-use Novice Agents, and five new trainers for use as supervisors or mentors.
