This is a great supplement if you or your PCs are interested in running a campaign centered around war. The overall design is nicely put together, though the page borders can be a bit much at time. This certainly doesn't detract from content though. There are about 80 pages of content giving some nice background and plot hooks for running a campaign as well as full encounters, new monsters, powers, feats. If you have a lot of PCs who are into martial classes, this would be a great supplement for your campaign.
