The first planned map pack DLC for Halo 4 will feature three new locations for War Games titled Wreckage – The manifestation of the chaos of war, Harvest – A canon concept brought to life-the doomed agricultural planet where humans first made contact with the Covenant, and Shatter – Themed around natural crystalline surfaces and the huge UNSC factories mining them.
The DLC will also include a brand new game mode called Extraction, a 5 vs. 5 objective-based game where each team must capture and defend various points by placing down a beacon on each point and waiting for the extraction process to complete.
If the defending team manages to successfully defend the beacon they have placed, they win a point. If the opposing team managed to interrupted the process and overtake the point before the extraction is complete the opposing team takes the point. Once the site has been successfully extracted another point is revealed and the fight begins once more until one team reaches 5 points.
The Crimson map pack will be available to download on the 10th of December and will set you back 800MS Points.
