Halo 4's first DLC map-pack, Crimson, lands on December the 10th, bringing three new multiplayer maps and eight new Achievements. The details of the latter have just dropped via Halo Waypoint. Better polish up that aeriel combat if you want them though. Jumping seems to play a rather large part.
The details? As below.

Size Is Everything
Kill 20 enemies with a detached Machine Gun Turret - 20 points
