It comes with loads of weapon options and lots of different ways to personalise your mighty war machines.

This is a ton of weapons, and it’s so nice that you’ll be able to arm your squads with the weapons you want! However the core plot is set in motion by Fulgrim and the Emperor's Children, who share the spotlight. He unwittingly becomes the keeper of a secret that could decide the victor in the developing galactic civil war. He has declared an agnostic worldview, the "Imperial Truth", which promotes science, rationalism, and human primacy.

The story's main character is Kai Zulane, previously a gifted Imperial astropath attached to the Ultramarines Legion.

The unauthorised visit is central to the story: apart from damaging the Emperor's top secret project ( Book 1) and the planet's defense, it massively disrupts Terra's long-range communications infrastructure.An ancient device has been found on Sotha, one which could guide the mighty warships out of the impenetrable veil that cut off Ultramar from the rest of the Imperium. Humankind's continuing biological and psycho-spiritual evolution includes the gradual development of widespread Warp-related psychic abilities that will make the species far more susceptible to Chaotic influence; united under the Imperium of Man, the Emperor seeks to protect all of mankind by using faith in the Imperial Truth as a shield.
