1. Make a backup from your save file and disable the steam cloud for GZ

2. Go ingame and store everything you wanna keep with your new Character in your Storage box ( Weapons, Ammo etc )

3. Go back to the Main menu and delete your character ( if you have more then 1 delete all )

4. Restart the Game !!! ( otherwise you will be on the same map as your old character )

5. Start the game and create your new Character. Now you will see ingame that you spawn at the first Location. Make your way to the first Save House with a Storage Box ( Iboholmen Church ). Look in your Box and profit.

Now the Downside i meantion before. all Challenges have to be done again, all Apparel you must collect again and also the Collectables. The biggest thing is you have no Realy Beacons to destroy. I don't know why this is a thing but these are the only things that don't come back. I hope it helps and don't forget. always make a manual backup from your save file. These are located here
