In the grim darkness of the far future there is only war...

Warhammer 40,000: Space Marine takes place in the brutal, science fiction setting of Games Workshop’s Warhammer 40,000 universe. In the 41st Millennium, humanity faces extinction at the hands of horrific aliens and demonic hordes. Only one force offers salvation, the superhuman Space Marines. Warhammer 40,000: Space Marine is an intense Action-RPG featuring epic battles where players take direct control of the ultimate defender of humanity, the mighty Space Marine.

The premium add-on pack, which has a suggested cost of 800 Microsoft Points / $9.99, will include a new Exterminatus mode called Chaos Unleashed. In this update to the popular co-op mode players will take on the role of Chaos Space Marine as they take the fight to both the Ork horde and Imperial Guard forces. With brand new boss rounds, new co-op arenas and new enemy units like the Imperial Sanctioned Psyker this mode is a must-have for players looking for a new challenge.

As well as the Chaos Unleashed Mode, the Space Marine add-on pack also includes three new multiplayer maps Habs Ablaze, Station Tertius and Aquila Canyon which can be played in all multiplayer game modes. The pack will also include ten new achievements and trophies.

In addition to the premium add-on content all players of Space Marine will receive a new multiplayer Capture the Flag Mode for free. Playable on all the game’s multiplayer maps, this team based mode challenges players to defend their flag while attempting the capture their opponent’s.

Jim Huntley, Vice President of Global Brand Management commented,“Space Marine offers a robust multiplayer experience out of the box but the addition of new maps, modes and challenges should keep the community playing for months to come.”

Alongside this add-on content THQ will be releasing a number of new player skins for sale on the Xbox Live, Playstation Network and Steam. Players will be able to purchase unique Salamanders, Alpha Legion, Legion of the Damned and Blood Angel skin packs for a suggested price of 240 Microsoft Points / $2.99 each.

The downloadable content pack for Warhammer 40,000: Space Marine scheduled to release for the Xbox 360, PS3, and PC in December.

Space Marine puts players into the role of one of humanity ’s elite soldiers, as they battle to protect an Imperial Forge World from a millions-strong Ork invasion. But this isn’t all that faces Captain Titus of the Ultramarines. When Titus makes planet-fall, he soon realizes that the forces of Chaos are lurking in the shadows pulling the strings for their own nefarious purposes.

The addition of Chaos forces adds more variety to the Space Marine single-player campaign by complementing the animalistic and horde-like Orks with a much more powerful and strategic enemy. While Titus can dispatch dozens of Orks alone, the Chaos Space Marines are more than capable of going toe-to-toe with him, especially with the support of Renegade Militia, Tainted Psykers and Bloodletter Daemons, among other units. 

Combining intense melee and ranged combat, Space Marine puts players into the boots of one of humanity’s elite soldiers, genetically engineered and equipped with state of the art weapons and armor. Players are dropped right into the action as they battle to defend an Imperial Forge World, from an invasion by the savage and brutal Orks, using the most devastating weaponry mankind has at its disposal.

You are a Space Marine, one of humanity’s elite warriors, the last line of defence between mankind and its enemies. Through extensive genetic modification, psycho-chemical conditioning and years of rigorous training that would kill a normal man a Space Marine becomes superhuman.

When one of the industrial ‘Forge World’ planets where humanity creates its greatest weapons, comes under attack and the thousands of imperial soldiers stationed there are overwhelmed the only thing standing between this planet and its total destruction is your Space Marine.
