Extraction

"In the game type Extraction, Spartan teams are tasked with the retrieval of assets from various sites using prototype translocation technology. Once a team has found a viable site, they must initiate the extraction process with a quantum marker and its spherical translocation beacon. As the extraction process occurs, teams must defend their beacon in order to prevent others from converting the existing extraction process into their own favor."

Extraction is a War Games gametype in Halo 4.

Description
Extraction is a 5 vs. 5 objective-based game type. Opposing teams have the objective of extracting Slipspace crates from various sites around the map. Players must plant a beacon using the specialised tool and protect it from the opposing team during the extraction countdown. If the defending team remains in control of the beacon, they receive one point, however if the opposing team "converts" the beacon, the point is theirs. Once a site has been extracted, a new site becomes available. The first team to extract five points wins.

Maps can be played on either a 1-site or 2-site variant, they are labeled as A,B,C, etc. and referred to as Alpha, Bravo, Charlie respectively.
