Built for one purpose. Hunt Evil. These guys are probably the most powerful single units that can be fielded in the game of Warhammer 40,000. Most Space Marines do not even have what it takes to join the ranks of the Grey Knights, for only this mysterious chapter of marines has had the necessary training and fortified their own strength of will enough to go toe to toe with the representatives of the four chaos gods.
These guys are more than capable of hunting other foes besides demons, though. They are simply the best outfitted troops in the universe, and have the training to make use of it. Always outnumbered but never overmatched, the Grey Knights will be a fun addition to any army, and a blast to play by themselves.
This full color, page for page scan includes everything you need to start sending out the Inquisition after the heretics of the Imperium. For anyone new to the hobby, make sure to grab my torrent of the current 5th Edition rulebook for Warhammer 40,000. Enjoy!
