Halo: Reach's new Defiant map pack launches on Xbox Live from 15th March, Microsoft has announced.
Like November's Noble DLC pack, it will cost you 800 Microsoft Points.
"Set in the heat of the legendary Battle of Reach, the three new warfronts Condemned, Highlands and Unearthed are primed for non-stop action in Firefight and all competitive multiplayer modes," read the announcement on Major Nelson's blog.
Reach launched on Xbox 360 late last year to widespread acclaim. "Reach is an encore, a victory lap, a crowd-pleasing last hurrah for a series that most definitely won't end here," wrote Eurogamer's Oli Welsh in his 9/10 review.
