In a game briefing presented to the media, Ubisoft described Assassin's Creed as a more linear game with a very story-oriented focus.

Like early works in the series, Fantasy is a game set in a metropolis, with the main location of Baghdad, which will be divided into 4 areas. In addition to Baghdad, players can also visit Alamut, the headquarters of the Invisible.

When designing the entire game world, the production team took into account both parkour and hidden needs, so IGN guessed that there might be many paths to the roof and hidden points. Ubisoft has also designed a new and more detailed enemy-seeking system that allows players to gain more information when sneaking.

Ubisoft said that some classic parkour moves in "Fantasy" will return, and they will run faster than the old games.

Returning to the classic game mode means that "Fantasy" no longer emphasizes RPG elements, but like the first generation "Fantasy" has a series of linear tasks, and players can freely choose which tasks to complete.

Some of these tasks are called "Black Box missions" by Ubisoft, which will be the main assassination mission in this game. Ubisoft did not give too many details in the briefing, but it was described as "an opportunity to choose the next target path and method." Some foreign media speculated that it might have referenced the assassination mission in "The Revolution", providing a variety of ways to allow players to penetrate the enemy area and approach and kill the target.
