Welcome to Part 3 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 bolster the defences of a last stand redoubt and cover an Imperial Guard army as it falls back from the outer defences! A tough task in this game that could end in a blood bath for the Imperial forces. Who will emerge victorious? Watch and see in this epic climax!
