I'm wrong about something.
You can use these save files in Plutonium T6. Just rename the .redacted file "mpstatsCompressed" and remove the .redacted file extension before putting them into the player dw folder inside the t6r folder. It WILL work. It's a means of saving your progress in the future too.
Now can we please get a file with all the Search and Destroy challenges and playercards completed?
