With their more successful title, Borderlands 2 coming out in September, the move seems to just avoid the two title going against each other, or avoid going against other big titles this year. It's a bummer I'm sure if you've been waiting for yet another Aliens game, but think of it this way - Delay means a more polish product. This is pretty much the third title pushed out of the 2012 line-up and placed in early 2013. Check the new trailer below.
Aliens: Colonial Marines' new release date is February 12, 2013 for Playstation 3, Xbox 360, and PC.
