Infinity Ward is on point with its new Extinction mode for Call of Duty: Ghosts and has just revealed the "First Contact" trailer to introduce the mode and its mysterious alien enemies.
As we previously revealed, the mode consists of four-player action, pitting a group of four human players against a race of invading aliens, Left 4 Dead style. It's not unlike the Zombies mode from the Black Ops series.
Call of Duty: Ghosts is set for launch on the PC and current-gen platforms on November 5 followed by releases on next-gen platforms at their launch.
