Call of Duty: Black Ops 3's Final Expansion Out Now on PS4

Salvation, the final expansion for Call of Duty: Black Ops III, launched today on PlayStation 4. It's not only the last add-on for the FPS, but it also ends the Zombies Origins campaign that started years ago.

The expansion includes four multiplayer maps, including completely new ones in the form of Citadel and Micro. The latter of those is particularly interesting in that it's basically Honey, I Shrunk the Kids, but in a Call of Duty sense. Another one is called Outlaw, and it's a western-style reimagining of the Standoff map from Call of Duty: Black Ops II. Rupture is the name of the fourth map; it's a reimagining of Call of Duty: World at War's Outskirts arena, but now its focus is a high-tech facility.

As for the Zombies mode, Salvation adds a chapter titled Revelations. This is the finale of the Origins Zombies saga that started eight years ago with Call of Duty: World at War. In this chapter, main characters Richtofen, Dempsey, Takeo, and Nikolai finally know the identity of Doctor Monty. This episode acts as a final showdown against "an ancient evil" in the "ultimate battle between human and undead."

Salvation is included with Black Ops III's $50 DLC pass or it can be purchased by itself for $15.

"The team at Treyarch has worked tirelessly to make this an incredible year for Call of Duty: Black Ops III players and we hope fans have as much fun playing it as we had making it," Treyarch boss Mark Lamia said in a statement. "The release of Revelations has a great deal of sentimental value: it has been an adventure eight years in the making, and a very special journey that we've taken with our fans."

For more on Revelations, check out GameSpot's interview with Treyarch senior executive producer Jason Blundell.

Salvation launches first on PS4 as part of a timed-exclusivity deal between Activision and Sony. If history is any indication, the expansion will come to Xbox One and PC in about a month.

Black Ops III's previous expansion packs included Awakening, Eclipse, and Descent. These are all included with the $50 DLC pass.
