Ubisoft is working on a new project codenamed Assassin's Creed Infinity, which will reportedly be an online platform that would include multiple historical settings and evolve over time – not unlike the approaches taken by Fortnite and Grand Theft Auto Online.
Bloomberg's sources say that Infinity is designed to run for years, and would include a number of settings, rather than the single historical locations the series is known for. The platform would seemingly encompass multiple different Assassin's Creed games, which "might look and feel different, but they will all be connected." Bloomberg's sources also say the project is years from release.
Ubisoft confirmed project's existence to Bloomberg, with a spokeswoman saying it wants to “exceed the expectations of fans who have been asking for a more cohesive approach”. No other reported details were confirmed.
