Any tips for the Golden Armor?

OK, I'm officially admitting that I need some tips on getting this dang golden armor because I am getting absolutely WRECKED every time I try it.

I've tried solo, duos, full squad, early round, late round, before the EE, after the EE, tried to sneak in mutant injections and chopper gunners, and for some reason I continuously get bodied. The one time I did get close it randomly just timed out and stopped and everything went back to normal......

Anyway, and tips, tricks, or advice would be appreciated lol
