The Horde of bloodthirsty orcs invaded the planet, a forge, which produces combat vehicles for the Imperium of Mankind. Space Marines, battle-hardened veteran of the Order of the Ultramarines Captain Titus and his party must keep the defense before the strike forces of the Imperial Navy. On the side of the enemy - a huge advantage in numbers, on the side of people - the best fighters and powerful weapons. The loss of the planet will give into the hands of the Orc weapon that can be washed to the ground entire towns. Defeat would not be justified, and the Space Marines ready to fight to the death, but something even more evil and horrible is hiding in the shadows of this world.
