Warhammer 40K: Darktide, the upcoming co-op shooter from developer Fatshark, has been gradually stepping up its marketing campaign. The new title will take the four-player action of Fatshark's previous title Warhammer: Vermintide and transport it to the series' sci-fi sibling. Darktide will be set in the depths of a hive city, a vast metropolis crammed with billions of Imperial citizens, wealthy nobles, and underhive gangers.
