"Call Of Duty: Black Ops 3 Salvation" DLC (Downloadable Content) map pack was released Thursday for Xbox One and PCs by Treyarch Studios. It includes four new multiplayer maps along with "Revelations" — the final chapter of the Black Ops Origins Zombies Saga.

Treyarch head Mark Lamia said in a statement: "Without a doubt, this is the most epic season of DLC that we've ever created for fans of Multiplayer and Zombies.”

Citadel

Citadel takes place in an abandoned castle. It is a mid-size map having close-quarter engagements and drawbridges for unique player movement.

Outlaw

Outlaw is a western style reimagination of the Standoff map from "Call of Duty: Black Ops 2." It is a mid-size map featuring classic engagements, flanking routes and strategic positions for long- and medium-ranged combat.

Micro

Micro features a miniaturized war zone that takes place on a well-stocked family picnic table.

Rupture              

Rupture is a revamped map that was first featured on "Call of Duty: World at War." It features a futuristic society trying to repair the Earth’s atmosphere.

Revelations — The Call of Duty official website states that four characters — Dempsey, Richtofen, Takeo and Nikolai — face a horde of zombies and are helped by the voice of Dr. Monty. The heroes need to put an end to the waves of undead running over the Earth, and in the finale, they will face off against Dr. Monty.

Salvation arrived on PlayStation 4 on Sept. 6 as a part of a timed exclusivity deal between Activision and Sony.

The Salvation DLC will be handed out free to lucky Season Pass owners. It will be available to others at $15. It is also available in combination with previous expansion packs including Awakening, Eclipse and Descent for $50.
