Respawn released an update for Star Wars Jedi Fallen Order that added a Journey+ Mode to the game. The mode is basically a game plus mode which allows the players to carry their progression in the second playthrough.
The May 4th update gives you access to the start of the game and carry your cosmetics items as you kick off your journey once again. You can use whichever costume for your main character and choose from any lightsaber you like. During this second play through all of the cosmetics boxes you found are empty so you don’t have any reason to explore the hidden nooks and crannies. However, if you haven’t found some chests you can still go after those.
Star Wars Jedi Fallen Order Journey Plus mode is available right in the main menu. Simply update your game and you can start the Journey+ mode in Jedi Fallen Order with ease. Star Wars Jedi Fallen Order on PlayStation 4, Xbox One, and PC. The latest Journey+ update is downloadable on all platforms.
