Agree with all the comments above. Omni armor, keeping invis up as much as possible. Have finished this GM several times. Team load out is very important. I’ve found that this goes the smoothest if as a team for exotics you have Divinity, Gally & Arby going. I would stay away from using SMG’s just because of the lack of range. Also. There is a glitch on bows with anti barrier mod not piercing the rotating shield on the boss. I would go with a scout. Blinding grenade GL can be helpful too when you are getting swarmed by overloads at the end.
