The Grey Knights are perhaps the most elite and secretive Chapter of the Adeptus Astartes, forged as the Imperium's greatest weapon against the dangers of the warp. In the Grey Knights' sequestered fortress on the moon of Titan, psykers and sages sift through omens of coming daemonic incursions – and despatch strike forces of daemon-hunting Space Marines, each gifted with well-honed psychic abilities. Aboard space hulks infested with unnatural entities, or voidcraft corrupted by their passage through the warp, the Grey Knights are an unstoppable force. Boarding Patrol: Grey Knights provides a balanced force of Space Marines infantry, perfectly suited to gunning and cutting down foes in games of Warhammer 40,000 – especially in the dense and deadly Boarding Action missions detailed in the Arks of Omen series – and will save you money compared to buying the kits individually.
