Tomorrow's a big day for gaming, between such anticipated sequels as Tom Clancy's Splinter Cell Blacklist  and Saints Row IV. However, another release is 2K Games' The Bureau: XCOM Declassified, which combines the strategic gameplay you've come to know from the series with an all-new action perspective.

To celebrate the game's release, 2K unveiled a new trailer for The Bureau, one that asks you to survive, adapt and win as you battle alien invaders. You can view the trailer below.

The Bureau: XCOM Declassified debuts tomorrow for Xbox 360, PC and PlayStation 3.
