A very useful product for fleshing out the Exodus campaign world, this title is a good supplement. However, there is considerably less in this than in the core volume.
There are some excellent faction information and some useful talents/feats, which are good for helping experienced GM's think up new organizations and settlements, or saving new GM's from having to do so on the fly.
Useful, not essential. At the full price this is an overpriced product, however it is almost always heavily discounted to a fair price. Would recommend for GM's looking to add extra flavor to a post apocalyptic setting.
[4 of 5 Stars!]
