Patch 1.06 for Dragon Ball Z: Kakarot is now live, bringing the long-promised Time Machine functionality to the game.
The Time Machine, located in West City to the right of the Capsule Corporation entrance, allows players who have finished the main story mode to revisit any of the past locations and story beats along the way; previously unfinished side missions can now be completed, though there are a few caveats as to which items you can bring and which special techniques will be available to you.
Developed by CyberConnect2 for Bandai Namco, the action role-playing game released 16 January 2020 in Japan and 17 January 2020 internationally on the PlayStation 4, Xbox One, and PC (via Steam). Earlier this month, Bandai Namco announced the game had shipped two million copies internationally.
Just a quick correction: you could already use Future Trunks before the Time Machine patch.
