Microsoft has now confirmed that  the Halo 4 Crimson Map Pack will be released on December 10th. Available for 800 Microsoft Points, the pack adds three new maps as well as the new Extraction game type and will be free to players who purchase the Halo 4 War Games Map Pass or to anyone who purchased the Halo 4 Limited Edition.

New maps include:

 

Wreckage

is the manifestation of the chaos of war. A medium-sized, asymmetrical map great for accommodating a wide range of objective-based game modes including King of the Hill and Capture the Flag. It is a ravaged environment of crashed debris, where the surrounding destruction creates complex paths perfect for throwing off your opponents, or testing the limits of your Warthog. This devastated landscape provides plenty of cover, with tons of nooks and crannies at your disposal while fighting for your turn to become King. Wreckage supports up to 16 players in Infinity Slayer and up to 12 players in a variety of other modes, including Capture the Flag, King of the Hill and Oddball.

 

Harvest

is a canon concept brought to life – the doomed agricultural planet where humans first made contact with the Covenant. A small to mid-size map, Harvest is ideal for Capture the Flag. Here, you’ll need to get creative to effectively use light vehicles which are limited to the exterior pathways and can’t get into the bases, making this map perfect for infantry firefights and face-to-face skirmishes. Snipers will also feel right at home; long sightlines are broken up by great cover and hiding spots. Harvest allows up to 12 players to face off in Capture the Flag, Infinity Slayer, King of the Hill, SWAT and Slayer Pro.

 

Shatter

is themed around natural crystalline surfaces and the huge UNSC factories mining them. This large, symmetrical map is a playground for the Warthog and Mantis – its open pathways make it easy to get around, whether on foot or in vehicles. Shatter is a great fit for Dominion and the new game type Extraction. For some close-quarters face-time, escape the open landscape and duck into a mining facility, or slip through a doorway and hunt unsuspecting Spartans. Shatter enables multiplayer mayhem for up to 16 players in Infinity Slayer and up to 12 players in other modes, such as Capture the Flag, King of the Hill, Dominion and Extraction.

 

Extraction mode

is a 5 vs. 5 objective-based game type where opposing Spartan teams are tasked with extracting assets from various sites around the map. Once a team has found a site and is in position, they must plant their beacon and protect it from the opposing team while the extraction process occurs. If the defending team remains in control of the beacon, they receive one point, however if the opposing team overtakes the site before extraction is complete, the point goes to them. Once a site has been extracted, a new site becomes available. The first team to extract five points wins.

 

Crimson Map Pack owners will have exclusive access to a single premium playlist that will only feature the new maps and will be the only place players can enjoy unique 6 vs. 6 matchmaking experiences, the new game type “Extraction,” and a wide range of voting combinations for different maps and modes.

 

Crimson is the first of three map packs, coming ahead of the Majestic Map Pack in February 2013 and the Castle Map Pack in April 2013
