Today, 2K Games released the trailer for 2K Marin's new game, XCOM
. 2K Marin were made famous with their last two releases: BioShock (Xbox 360)
and BioShock 2 (Xbox 360)
shares some details with 2K Marin's last game, namely it's art-deco 1950's art style, which coincidentally looks similar to Team Fortress 2, as well as it's first person shooter gameplay. The trailer also revealed one of the enemies you will be fighting (and studying). But I won't ruin that for you, check the trailer out on the external link (there might also be a glance at the death ray in there).
XCOM is currently lined up for a 2011 release.
