Call of Duty: Ghosts Onslaught DLC will be available on Playstation 4, Playstation 3, and PC on February 28.

The DLC was formerly released for Xbox 360 and Xbox One in late January.

Onslaught contains four new maps and two new weapons, and comprises the first episode in Extinction, a four-part episodic story.

Onslaught costs $15 as a stand-alone or incorporated into the game's season pass.

Episode 1, Nightfall, takes gamers to a remote research facility hidden deep within the Alaskan wilderness, where a small recon team must break into the facility to find out what happened to the covert Nightfall Program. This expanded Extinction storyline presents new characters, plus two brand new alien species, and introduces an exclusive Venom-X weapon that crushes the Cryptids, as players delve deeper into the story of what happened after mankind's first contact with the Cryptids in Colorado.

The new maps are explained in the official press release:

"Fog: A chilling tribute to classic horror films, set alongside the banks of a murky lake, gamers skilled enough to discover the map's exceptional Field Order can become the personification of evil and don the mask of Michael Myers, one of film's most legendary horror characters from Halloween movie franchise."

"BayView: A coastal Californian boardwalk that offers gamers fast-paced run-and-gun gameplay inside a seaside town. Skilled gamers will be able to climb onto the map's moving trolley to combat enemies, in addition to call in devastating artillery strikes from the Naval Destroyer anchored offshore."

"Containment: This map drops players into a raging clash inside a war-torn Mexican village, where the action centers on the crippled remnants of a small bridge holding a hi-jacked truck leaking radioactive material."

"Ignition: Onslaught's fourth and final newest map is a entirely reimagined version of "Scrapyard" - the fan-favorite multiplayer map from Call of Duty: Modern Warfare 2, placing players into a abandoned space launch facility with frenetic action amongst abandoned warehouses, flame trenches, a massive transport crawler, and vibrant map elements that can take players out if they are not paying attention."

"The brand new Maverick gun is equipped with a lightweight wood stock and a digital screen display, and can be used as an assault rifle or sniper rifle."
