There is also plenty of dramatically lit shots of miniatures to compliment the descriptions. Including a couple of better images of what appears to be an upcoming Terminator Captain. We also get a brief description which confirms that he is in fact a generic Captain and not a special character. With no news of any other Space Marine upcoming releases, it will be interesting to see how this guy get released, are Games Workshop looking to do another Web Exclusive?
Update: We also have confirmation that this Captain will be arrive on the 31st May from some pictures from the upcoming White Dwarf.
If this early access is accidental then my advice would be to grab this sample before somebody realizes their mistake. Even if you find that it doesn't have much relevance, you cannot grumble at free stuff. The eBook editions for both the iPhone and iPad feature full access to the A Galaxy Of War. The interactive edition for iPad however, features a limited number of pages from A Galaxy Of War but does show a few pages from the other two books. The preview of Dark Millennium, the background book, shows that this will be full of excellent looking artwork like the image below:
