A tease from developer Treyarch seems to suggest Outbreak, a Call of Duty: Black Ops Cold War Zombies mode, will soon receive a day/night cycle. This is a big week for Black Ops Cold War, given the return of the R1 Shadowhunter crossbow in the latest update. Other major changes are on the horizon as well, namely in the form of a new region for Outbreak's Ural Mountains map. The next update will also introduce a brand-new objective and fresh intel, though specific details related to both are being kept tightly under wraps for the time being.

Following a series of teasers and Easter eggs, Treyarch deployed Outbreak mode in late February, providing players with a large-scale Zombies experience that worked to continue the Dark Aether arc. New enemies and objectives also joined the fray, alongside missions that required players to track down dimensional portals and hunt foes using satellite trackers. Outbreak's next update may take the chaos of Zombies gameplay yet another step further.

Yesterday, Treyarch shared a quick Outbreak-related tease, hinting at the arrival of a new region, objective, and intel. A gif accompanied the studio's social media post, offering a sneak peek at footage of what appears to be the Sanatorium map. Another line of text featured in the tweet appeared as follows: "Think you can survive the Ural Mountains after dark?" This suggests the mid-season update will add Sanatorium as a new region in the Ural Mountains locale. The general consensus is that Treyarch's "after dark" line may additionally serve as evidence that a day/night cycle will launch with the update. Yet, as of writing, the developer hasn't confirmed as much. See the cryptic post below:

Of course, there's also the possibility that a full-on day/night cycle isn't in the works at all. Treyarch could simply be teasing that a nighttime map for Sanatorium is on the way. That won't become clear until the studio releases more concrete information, however. Regardless, it seems as though Black Ops Cold War fans will soon have yet another reason to explore the horrors of Outbreak.

Black Ops Cold War launched late last year as a cross-gen release. To the surprise of no one, the first-person shooter instantly topped the sales charts and remains a top-selling title across multiple markets. And hype is already building for this year's Call of Duty entry, which rumors claim will return the franchise to World War II.
