Permanent Steel barricade perk question

[game78]

So i was wondering has anyone done this solo and it stayed permanent or should i do this with someone else?

Well idk I did it in custom games solo and I unlocked it there. I played online and I didn't have it. Then I got the green bast and I know have it in co-op. So I am guessing you have to do it for that mode?? Although the quick revive one isn't like that.

I got it in custom and have it in both custom and public games so I don't know. For my friend he got it in public and has it in public but doesn't have it in custom.
