How to transfer your WWZ saves from Epic Games to Steam

Method #1

Use official PROS service:

1. Visit: https://prismray.io/games/wwz
2. Link the game to a PROS account.
3. Go to Save Transfer section.

Method #2

Transfer files manually:

1. Your save file from EGS is located here: c:\Users\<USERNAME>\AppData\Local\Saber\WWZ\client\storage\
2. Open the folder with long name that consists digits and letters, for example, 7e6ff88fcea547e1a8a26760d8571455. The file you are looking for is user_progression.dat.
3. Open the Steam Cloud directory for World War Z: c:\Program Files (x86)\Steam\userdata\<YOUR_STEAM_USER_ID>\699130\remote
4. Delete the user_progression.cfg file located in the Steam folder and replace with the user_progression.dat from EGS. Change file extension from .dat to .cfg.
