Activision has unveiled the final DLC pack for Call of Duty: Black Ops III, Salvation, and released a new trailer for its Zombies content.

The pack is comprised of four multiplayer maps, as well as Revelations, the new Zombies mission that concludes the ongoing Zombies storyline. The new trailer makes it look awfully good, even to me as someone who hasn't been a big Zombies mode player. Check it out above.

"In Revelations, we meet up with the Origins characters after they've taken an epic journey through space and time--all of their struggles lead to this very moment," states a press release. "In this, the final chapter of the Zombies experience, Richtofen, Dempsey, Takeo, and Nikolai finally come face to face with the mysterious Doctor Monty in The House. Confronted by an ancient evil, our heroes must fight the zombie horde once more in the final battle to save their immortal souls."

Zombies director Jason Blundell adds, "With the release of Zombies as an Easter egg in 2008's Call of Duty: World at War, Treyarch set forth on a journey--or, really a conversation--with fans, and Revelations is the final punctuation mark. The secrets we laid out years ago will finally make sense--we've been waiting a long time for this."

Blundell told GameSpot recently that a years-old Zombies cliffhanger would be resolved in this DLC.

Also included in the DLC are the aforementioned multiplayer maps. Two of these are original creations, while two others are reimagined versions of maps from previous Treyarch Call of Duty games. Here are the official descriptions:

Citadel: Once home to a powerful medieval army, this ancient castle now sits broken and abandoned. Tight corners force close-quarters engagements, while the moat and drawbridge allows for unique player movement opportunities in this mid-sized map. The last trespassers didn't make it out alive--maybe you'll have a better shot.

A miniaturized war zone that takes place on a well-stocked family picnic table, that's what! Navigate this bite-size battlefield for a larger-than-life experience.

Outlaw: Gear up for a showdown in Outlaw; a western-style reimagining of the fan favorite map Standoff from Call of Duty: Black Ops II. This rough-and-tough medium-sized map brings classic engagements, flanking routes and strategic positions for long and medium ranged combat.
