Currently on The Maw, my co-op partner did it without me ( ) and 6 shell shotguns solo is quite a pain, anyways leave your GT if your interested as after all you get to skip 9 missions. Note that i’m in the UK so it maybe a while to get back to you. Only need one player so sorry if I found someone. Peace.
if you still need help I am up GT is FightingSmile64
