You can , Its just glitchy.
If you prestige hack on any of the characters, It will change all of them (BUG)
You can downrank yourself. prestige wise, it will do it for all of them, But you can change level which is nice,
Squad points is a sure yes for working Loving it.
Hope this helps Improving this hack
I was under the impression that prestige is per an account and not a character but I will check on this however the fact that one address changes all would say it is per account.
The buggy part is it does not show immediately and takes a few seconds to show on screen or you have to go onto another game screen to see the changes, this is not a bug in the cheat but how the game displays changes within the game.
I clicked the Unlock All Characters and the Unlock All Loadouts button, after I had already bought all the characters using a squad point hack, now whenever I go to my soldiers I only see the first one and all the others are just blank, any way to bring them back or undo that part of the hack?
EDIT: Forgot about the part where I'd have to change there names, my bad. Problem solved!
I had to make some alterations to the code for it to work on here as vanilla it leaves the character blank, I had it so it named the character but it advertised another site so had to remove that naming section.
All you have to do is rename your character, as that option is available in game
