The Bureau: XCOM Declassified Gets A Story Trailer Mixed In With Gameplay

2K Games has put out a new trailer for 2K Marin's upcoming tactical third-person shooter, The Bureau: XCOM Declassified. Titled "Last Defense", the trailer showcases the game's strong emphasis on strategy and teamwork as players are sent into the field to combat the alien menace and erase their existence from human history before word gets out about their presence on Earth. 

Set in the 1950s, the game takes place many years apart from XCOM: Enemy Unknown. It's not yet known how the two games will tie in together in terms of story, but we can expect to find out more about the connection between the two as more details become declassified by the folks at 2K Marin. 

The game is set for an August 20 release in the United States, and is available on the PC, Xbox 360 and PlayStation 3. Europeans will have to get the game a few days later, on August 23.
