According to a source, it appears that Ghostwire Tokyo developers Tango Gameworks are working on a mini-game as described. It is expected to be revealed at the next Xbox event, which is rumored to take place in early 2023.
Shinji Mikami, head of Tango Gameworks, said in a previous statement that services like Xbox Game Pass encourage developers to work on smaller-scale projects with ideas that are different from massive AAA games. And it seems he meant what he said, as the latest rumors indicate that his team is working on a smaller-scale game, like the recent Xbox exclusive Pentiment.
Leaker Jeff Grubb claims the studio is working on a minigame, but didn't provide any additional details about the project. But we already know that Tango Gameworks has more than one secret project in the works. It's also working on the Xbox version of Ghostwire Tokyo, which launched exclusively on PS5 last March.
This news, if true, may disappoint players who are waiting for the announcement of The Evil Within 3 game project. Shinji, who is the spiritual father of the Resident Evil series, created the said series and was very successful among players.
There is still nothing confirmed, especially with regard to the aforementioned leak, whose leaks often turn out to be true. Let's wait for the next few months to see if Xbox will host an event, and then we will see if the studio will show up with its new project.
