Welcome to Part 2 of our 2nd Warhammer 40K Campaign as the scuttling Tyranid horde overruns an Imperial planet. This time the Ultramarines led by Captain Cato Sicarius must protect an Imperial Guard convoy as it winds its way through a ruined part of the city! Will the Tyranid stampede obliterate the vulnerable Imperial column? Or will the Ultramarines be able to coordinate a well improvised protective shield? Watch and see!
