HALO: Envoy

While the Master Chief defends a besieged Earth, and the myriad factions of the Covenant continue their crusade to eliminate humanity, an ultra-secret cell of the Office of Naval Intelligence, known as Section Three, devises a plan to buy the UNSC vital time. They're going to need hundreds of willing soldiers, though...and one more Spartan to get the job done.

Set 300 years after the events of Alien: Out of the Shadows and Alien: River of Pain, Alien: Sea of Sorrows deals with the rediscovery of dormant Xenomorphs (Aliens) in the abandoned mines of LV-178, the planetoid from Alien: Out of the Shadows, which has now been terraformed and renamed New Galveston. The Weyland-Yutani Corporation, reformed after the collapse of the United Systems Military, continue their unceasing efforts to weaponise the creatures.

In barren desert lands and seedy spaceports...in vast underwater cities and in the blackest depths of space...unfolds a tale of good and evil, of myth and magic, of innocence and power. At last the saga that captures the imagination of millions turns back in time to reveal its cloaked origins - the start of a legend - the story of Star Wars.

When the Colonial Marines set out after their deadliest prey, the Xenomorphs, it's what Corporal Hicks calls a bug hunt - kill or be killed. Here are fifteen all-new stories of such "close encounters", written by many of today's most extraordinary authors. Set during the events of all four Alien films, sending the Marines to alien worlds, to derelict space settlements, and into the nests of the universe's most dangerous monsters, these adventures are guaranteed to send the blood racing - one way or another.

The Covenant mission is the most ambitious endeavor in the history of Weyland-Yutani. A ship bound for Origae-6, carrying 2,000 colonists beyond the limits of known space, this is a make-or-break investment for the corporation - and for the future of all mankind. Yet there are those who would die to stop the mission. As the colony ship hovers in Earth orbit, several violent events reveal a deadly conspiracy to sabotage the launch.
