In the dark universe of Warhammer 40,000 humanity's Imperial empire stretches across the Galaxy, holding over a million worlds. Many of these planets suffer raids, rebellions and as great as system-conquering invasions. The planet Gria is a world completely dedicated to manufacturing technology, weapons and equipment for the Imperial Guard - the military might of the Imperium. Once Gria is invaded by a horde of Orks (a race of brutal, vicious ape-like creatures) the Guard suffer tremendously in their defense. A force of Space Marines - genetically enhanced and fearless warriors - from the Ultramarine Chapter is dispatched to aid in protecting the planet's most valuable weapons and resources, most importantly the Warlord Titan 'Invictus'. You are Captain Titus the commander of the Ultramarine Forces, aided by squad mates: Sargent Sidonus and Brother Leandros, who soon find themselves aiding a mysterious agent with a dangerous and vital project.
