Found this cool news article discussing possible teasers for the next new map coming out in February: MSN
While official confirmation is still pending, players have uncovered several subtle teasers suggesting what the map might entail. Among the most compelling clues is a new voiceline exchange between Lifeweaver and Orisa. In the interaction, Lifeweaver asks Orisa if she has been to “the arcology,” to which Orisa replies that her creator, Efi, had once spoken at a conference held there.
This isn’t the only hint pointing to the mysterious Atlantic Arcology. Within the Midtown map, Hyper-rail trains reference the underwater locale, suggesting a possible setting for the new map. Should this be true, it could mark the debut of the first officially designed underwater map in Overwatch 2. While Blizzard briefly showcased Talantis, a community-designed underwater map, this would be the first one designed directly by Blizzard to enter competitive rotation.
This Atlantic Arcology map sounds really interesting! To me, it sounds like it will look like Atlantis. Is this concept map the inspiration for the Altantic skins? The Atlantic Arcology map could also have lots of water. Perhaps the map will be interactive with waterways allow water to travel between different areas of the map, perhaps making dynamic environmental water-based hazards.
What do you think the new map in February will be?
It’s not gonna be an underwater map, though the arcology is described as having underwater sections. It’s basically a city in the middle of the ocean consisting of a giant spire in the centre with artificial islands dotted around it.
They added a poster for it in the Numbani airport when it got reworked (Along with a poster for Morocco) so yeah it should be one of the next maps. Hoping for Flashpoint personally
I don’t know, it’s an interesting idea but I don’t understand why there would be an Atlantis in the world of Overwatch. It seems like a common overused thing in sci-fi.
Sure, the game is set in distant future of today and there’s already a sort of technological-fictional city of Numbani. Which honestly could be any normal city with new tech 50 or so years from now. But I don’t know about some ancient underwater tech city, unless it’s a sorta underwater laboratory like the lunar and mars colony.
If it’s true and it becomes a thing, I just want to know how it fits to the world and why. What kind of characters are going to be there? What is their technology? What’s the drama that pushes characters to fight? How does it relate to Overwatch organization and the other heroes? That kind of thing.
I’m sure a map there would look cool either way but gameplay wise I doubt we’ll be swimming around lol
I dunno, I think the arcology is perfectly fine as described and that we shouldn’t be retconning things unless it’s absolutely necessary like with Kiriko’s age.
Perhaps the map will be interactive with waterways allow water to travel between different areas of the map, perhaps making dynamic environmental water-based hazards.
