Bloodline

This article is about the multiplayer map. For the comic series, see Halo: Blood Line.

Bloodline is a multiplayer map in Halo 2: Anniversary. It is a remake of Coagulation from Halo 2, with some minor changes. Coagulation is one of the seven Halo 2 multiplayer maps that have been completely re-imagined in Halo 2: Anniversary.

Changes from Coagulation to Bloodline

 * The bases and other structures on the map are now of human construction, whereas Coagulation and all previous Blood Gulch remakes and reimaginings are based in Forerunner locations.
 * The bottom floor of both bases has been removed and the bases are more simple in design. Both team's base can be entered from a hole in the flooring. Man cannons have also been added to each base, replacing the teleporters on the original map. A red or blue beam is emitted on a cliff behind each base; the beam's color matches the nearest base.
 * A device has been added near the center of each base. When activated, it releases an EMP burst to the surrounding areas of the base that disables all vehicles within range.
 * An AV-14 Hornet and the M274-M Gungoose have been added to the map. The M808B Scorpion has been removed by default, although it can be enabled. An M7S SMG has been added to the ramps of the bases.
 * Deployable vehicle access bridges have been added next to the bases.
 * The central area of the map now houses a bunker, titled the "UNSC Training Bunker", embedded in the terrain. It is the location of an M90 shotgun.
 * Three trees on the original Coagulation have been replaced by three broken-down concrete pillars.
 * Extra rocks have been added to the map to provide more cover.
