The Bureau: XCOM Declassified is less than two weeks away. As the release nears, the team at 2K Marin has opened up a bit more about the long road the game has taken.

In the latest developer diary, we learn how the art evolved to capture the essence of the XCOM franchise while also staying true the 1960s setting. The creepy alien designs are more detailed versions of series standards.

The mission settings take inspiration from The X-Files and period pieces like Mad Man. You can learn more in the video below and take on the alien threat on August 20, when The Bureau: XCOM Declassified arrives on PlayStation 3, Xbox 360, and PC.
