Less than two months ago, 2K Games announced The Bureau: XCOM Declassified, a third-person shooter that reveals the origins of XCOM organization featured in last year’s XCOM: Enemy Unknown. The game’s August release date is still two months away, but 2K today announced its plans for pre-order and post-release DLC. Specifically, 2K is promising “narrative-driven” DLC that expands upon the story in The Bureau.

“The alternate 1962 universe that we’ve created for The Bureau is vast and there are many more stories to tell about the early days of XCOM,” said Morgan Gray, development director at 2K Marin. “We’re excited that our stories will provide a new perspective on the war effort, much like how our critically acclaimed Minvera’s Den DLC for BioShock 2 allowed us to present a unique perspective of Rapture.”

2K announced those who pre-order the game will receive the exclusive “Codebreakers” DLC mission, which sees agents battling aliens for control of a secret government communications facility. The light plasma pistol in-game item also comes with a pre-order. Though the game is also coming to PlayStation 3 and PC, the first Bureau DLC pack will be released first for Xbox 360 players.

As part of its announcement, 2K today also released a gameplay trailer for The Bureau. It shows how some of the classic XCOM strategy elements have been integrated into what otherwise appears to be a Gears of War-style third-person shooter:
