Call of Duty developers Treyarch have offered players a slight glimpse at what could be potentially coming soon to Black Ops 4's Battle Royale mode.
On February 18, Treyarch officially announced Operation Grand Heist, the next major content stream in Black Ops 4 that will bring a slew of new content for the game's three core modes - Blackout, Multiplayer, and Zombies.
The announcement included a trailer which summarizes everything that players can expect from this Operation, but many are focusing on a very short teaser offered towards the end of the video.
There is a slight moment near the end where the video cuts to a scene that shows a bunch of players gliding down in the dark towards an ominous looking structure.
Despite the very short nature of the teaser, there is no mistaking that it's for Blackout because of the immediately recognizable wing-suits that all of the characters are using to glide down.
Of course there are two main points of speculation drawn from this mini teaser, with the main being that it shows Blackout at nighttime.
Since the game's release, the Blackout map has only featured a singular weather, time of day, and lighting, and there hasn't really been much talk about a night map up to this point.
However, there is no mistaking that the video clearly hints at some sort of nighttime version of the map coming at some point, although it's not clear as to whether it will be featured in a limited time mode or the game's core default modes.
The second aspect of the teaser that many are talking about is the ominous looking building itself, which many are speculating could be the infamous Alcatraz Prison, or some sort of knock-off version of it.
Despite being out of operation now for a long time, Alcatraz Prison is arguable the United States' most well-known prison, located on the treacherous Alcatraz Island in San Francisco Bay, California.
At close glance, the building and its accompanying watchtower shown in the teaser closely resemble the infamous penitentiary, so the theory definitely has some sense to it.
The resemblance isn't the only thing sparking this speculation; the final instant of the teaser shows a Zombie running in what appears to be a prison cell-block.
While the Alcatraz connection may be just a theory at this point, the nighttime map is certainly and clearly hinted at in the official video, so it's a good bet that it may be added at some point in the near future.
