the Death Star. Random encounters may occur in the game's hub world. For example, an Imperial Star Destroyer could suddenly jump out of hyperspace and send a fleet of TIE fighters after the player. Players can choose to engage in dogfights with them or continue onward to progress the story. Lego Star Wars: The Skywalker Saga does not feature a character customization tool unlike many previous Lego video games. The game also includes Mumble Mode, an extra feature allowing players to switch between the game's original voice acting and having the characters mumble and grunt, akin to the style of older Lego video games. Development The Walt Disney Company and Lucasfilm had not shared significant details of the film Star Wars: The Rise of Skywalker with the game team before the film's release. In the meantime, TT Games worked on other aspects of the game until Lucasfilm shared more details. The game is developed in TT Games' new proprietary game engine, NTT (pronounced "entity"). On 20 January 2022, a report published by Polygon detailed the amount of crunch that occurred since the game began development back in late 2017, including dozens inside the company being at odds with management, due to expressing frustration over tight development schedules, the company's crunch culture, and outdated development tools. In addition, the use of NTT was controversial within the company, as many employees had been pushing to instead use Unreal Engine. NTT turned out to be incredibly difficult to use, with some animations taking hours more to produce than they would on the old engine. As a result, Lego Star Wars: The Skywalker Saga would end up being the only game developed by Traveller's Tales to use NTT, with the company deciding to use Unreal Engine going forward for their future projects. Like Lego Star Wars: The Force Awakens, Lego Star Wars: The Skywalker Saga features original voice acting, with some actors reprising their roles from the films and television series. The game also marks Tom Kane's final acting credit, due to a forced retirement in the wake of his stroke in November 2020. Release Lego Star Wars: The Skywalker Saga was first teased to be in development by Lucasfilm sound editor Matthew Wood at Star Wars Celebration Chicago. An announcement trailer premiered at E3 2019 during Microsoft's press conference. A second trailer showing one scene from all nine movies was released on 20
