Assassin's Creed could visit ancient Rome in a game codenamed Mars, while a separate mobile project called Pocket is reportedly set in Jerusalem. Neither game has been announced by Ubisoft, and the claims do not establish a release date for either project.
The rumor comes from content creator j0nathan. According to Eurogamer's report, he says two sources with access to Ubisoft's backend systems corroborated the Rome project. Eurogamer also notes that Insider Gaming had heard the codenames but could not confirm them sufficiently to report them independently.
Pocket is described as a smaller, challenge-based mobile game, with comparisons to Assassin's Creed Valhalla's Mastery Challenge. That would make it a different proposition from another full-scale open-world entry. The mobile format is part of the leak, not an announced platform commitment; Mars has no confirmed platform list.
Ancient Rome would also be distinct from the city players explored in Assassin's Creed Brotherhood, which used a Renaissance setting. The alleged projects are separate from Codename Hexe, Ubisoft's already announced darker Assassin's Creed game.
What Ubisoft has actually said
Ubisoft's October 29 franchise update provides some relevant context. The publisher said its teams are working on unannounced projects with new settings and stories, while stating that no other Assassin's Creed remake is actively in development. That leaves room for new games, but does not verify Mars, Pocket or their alleged settings.
The same update said the next major Hexe update will arrive in 2027. That is a timing commitment for more information, not a release window, so the new rumor does not supply a reliable order in which these games might launch.
There is an official Roman connection elsewhere in the franchise: Ubisoft said production on Netflix's live-action Assassin's Creed series was nearing completion in Rome and referred to its Roman Empire setting. j0nathan reportedly believes Mars will be connected to the series, but Ubisoft's update did not announce a companion game. It also gave no release date for the show.
