Xbox owners had a headstart with Call of Duty: Ghosts' Onslaught DLC, getting the first opportunity to save Alaska from aliens and terrorize soldiers as Michael Myers. But their window of exclusivity will end on February 27 when Onslaught arrives on PC, PS4, and PS3.
Onslaught features four new multiplayer maps, including the aforementioned Halloween-inspired Fog, Bayview, Containment, and Ignition. It also includes the first episode of the new Extinction campaign that sees an alien menace invade the Alaskan landscape.
Season Pass owners will get Onslaught at no extra charge, otherwise it'll be available for $14.99.
