As Ubisoft is betting even bigger on the franchise, there are reportedly multiple Assassin's Creed projects in the works, but at least some of the rumored settings are tied to Assassin's Creed Infinity, a live-action game that players will be able to explore several settings.
Assassin's Creed Red is said to be part of Infinity and set somewhere in Asia. The exact location has yet to be established, although reports suggest that Japan is possible. However, given the wide berth that Asia has, there are plenty of locations that would make excellent settings in Red.
Assassin's Creed Red: Japan
According to initial reports on Assassin's Creed Red, Japan is the most likely location. Given how fans have demanded it for years, and how Ubisoft has even teased it itself, as far back as Assassin's Creed 4: Black Flag, this would be the most obvious winner.
Assassin's Creed Red: India
India would be another good choice. Although Ubisoft has technically taken the franchise to India before, that was in a spin-off game, and yet India has always had an important role with the Brotherhood. Assassin's Creed Syndicate explores Sir Henry Green, an Indian-born member of the Assassins, or his ancestors, the whole region is ripe for a main game.
Assassin's Creed Red: Persia
Assassin's Creed has flirted with Persia (modern-day Iran) several times, the most prominent being Darius in Odyssey's Legacy of the First Blade DLC. This chapter of the Assassins' history would be unusual, given its end was marginally discussed, compared to everything seen thus far.
Assassin's Creed Red: The Philippines
There's also the possibility to explore locations that Ubisoft hasn't teased as heavily. The Philippines is one such location, which has a ton of history, but little concrete content. Along with the region's history, the Philippines would be a great place to explore the Brotherhood.
Assassin's Creed Infinity is in the works.
