Despite the recent news that Red Faction is going to be phased out, THQ at least appears to still be supporting the most recent release in the franchise, Red Faction: Armageddon, as today marks the release of a new DLC add-on for the game titled "Path to War".
Here's the description of the new content from Xbox.com:
The Earth Defense Force has been defeated, and after centuries of oppression, Mars is finally free. For a time, there was peace. Yet from the forgotten ashes rose Adam Hale, scarred from years of struggle, seeking ultimate revenge against the Red Faction. His target, the one thing that keeps the surface of Mars habitable for thousands of colonists, is the Terraformer. Relive the battle for the Terraformer through four incredible new missions featuring aerial flyers, orbital strikes, and the Red Faction armored surface tank. Unlock two destructive new weapons, the Sharpshooter Gun and Shard Cannon, while earning ten new achievements in this thrilling new mission pack for Red Faction: Armageddon!
"Path to War" adds 10 achievements worth 250 GS and will set you back 560 MSP. You can download the add-on right here.
