Space Marine Battles: Warhammer 40,000

When the ork hordes of Warlord Snagrod lay waste to the planet of Badlanding and wipe out the Crimson Fists Space Marines sent to halt their advance, Chapter Master Pedro Kantor must prepare the defense of the Chapter's home planet, Rynn's World. Tragedy strikes when an errant missile destroys the Space Marines' Chapter monastery, killing many of their remaining warriors. With only a handful of Crimson Fists left, Kantor must fight the campaign of his life, to defeat Snagrod's orks and prevent his Chapter's annihilation.

Captain Kor'sarro Khan of the White Scars is petitioned by his Chapter Master to hunt down and destroy the daemon prince Voldorius, a warleader of the renegade Alpha Legion, thus ending his reign of terror across the stars. Hunting the beast doggedly for over a decade, Kor'sarro finally brings Voldorius to battle on Quintus, a world that has totally given itself over to the Alpha Legion. Together with their Raven Guard allies, the White Scars must fight an entire planet if they are to slay the daemon prince.
