Seekers will find you in this XCOM: Enemy Within trailer

Firaxis showed off and discussed XCOM: Enemy Within in front of a gibbering crowd of alien-tactics-loving PAX goers today, and we've got the new trailer to prove it. Check out the video below for your first look at the predatory Seeker enemy.

Will XCOM's new mechanically and genetically augmented soldiers be enough to deal with these new threats? That's up to you to decide, commander.

Enemy Within will release on November 12 as a PC expansion for XCOM: Enemy Unknown for $30, and bundled up with the original game on PS3 and Xbox 360 for $40.
