The second DLC for Halo: Reach, the Defiant Map Pack, will hit Xbox LIVE for 800 Microsoft Points on March 15. The pack features three brand new battlefields—Condemned, Highlands and Unearthed Set—all set in the Battle of Reach. Players can put it down in all three in Firefight and all competitive multiplayer modes. If for some reason you still haven’t copped Reach yet (cryogenic mishap, full-body cast, stint in a space station orbiting the planet), you're in luck: today only, Amazon has cut the game's Legendary Edition—normally $150—to $60, and the Limited Edition version from $80 to $40.
