From publisher blurb:
Living in Syn is a companion to Crystal Heart, presenting several new systems and suggestions for both players and GMs:
Further Training presents new possibilities for character creation, including powerful roles, and a set of training montage tables to help create crazy-awesome backstories.
Exploring Crystals suggests new Setting Rules for handling Crystals, including a variant rule that requires an Agent to sync-up with their Crystal before they can use it fully.
Synfull is a big chapter, with lots of alternative systems for Requisition, such as switching to more abstract Supplies levels which can become anything you need. It also suggests new things to buy, such as special services and consumable power-ups.
Game Mastering Syn provides a thorough list of suggestions and concepts for groups who want to put more emphasis on playing a part of a bigger organization in general, and Syn in particular.
More Tales has some more Savage Tales we didn’t have room for in the core book.
The Appendices present eight ready-to-use Novice Agents, created by some of the backers of the Crystal Heart Kickstarter, as well as five new trainers to be used as supervisors or mentors.
