CITIZENS OF THE COMMONALITY!
It’s a time of adventure, a time of opportunity! A time for humankind itself to change! Join us, in the hyperadvanced worlds of the Core or the chaos and conflict of the Fringe, and reach for the stars! No one knows what the future will bring—but in the pages of this book every agent of the Commonality will find what they need to survive and thrive in the Rediscovery of Humankind.

The Mindjammer Player’s Guide is a rules book for Mindjammer—The Roleplaying Game, intended exclusively for the use of players. 

It contains:

-All the rules you need to create and play characters in the Mindjammer universe. You can even play a sentient starship!
-Descriptions and histories of the New Commonality of Humankind.
-New starmaps, homeworlds, and genotypes of Commonality Space.
-Rules for the Mindscape and virtual worlds.

Charge your blaster, thoughtcast your orders to the starship sentience, and fire up the planing engines. Come and defend the light of humanity’s greatest civilisation as it spreads to the stars. The universe awaits!

The Mindjammer Player’s Guide contains everything you need to play as a player in a Mindjammer game. If you want to be a Mindjammer gamemaster, please see the Mindjammer—The Roleplaying Game core book instead!

Note that while it does contain some new content, the Mindjammer Player's Guide reiterates much of the material of the Mindjammer - The Roleplaying Game Core book. You don't need the Player's Guide if you already have that book - although your players may love a copy!
