Behind the scenes: Halo: Reach's Defiant Map Pack

Certain Affinity and 343 Industries have released a behind-the-scenes video documentary that offers a detailed look at the maps that make up March 15th's Defiant Map Pack for Halo: Reach.

Members of Certain Affinity - the development studio behind this particular map pack - talk us through each map in detail and the decisions they made in making them, while also giving us a glimpse at what you can expect when you fire them up on March 15th. In fact, it's a little more than a glimpse; there's close to 11 minutes' worth of footage in this clip.

The Defiant Map Pack consists of three new battlegrounds: Condemned, Highlands and Unearthed (a map designed exclusively for the game's Firefight mode). The pack will be available to download on Xbox LIVE from March 15th.
