Anyone wanna help me with Chapter 7 Nightmare/Be a ***?

Hey guys. I beat the game, got all the 300,000+ kills or whatever ridiculous amount it was and I loved it. But I still need the Be a *** and beat Chap. 7 on nightmare, so I think if someone invites me to their co-op game just for that chapter it counts.
I just have a few other games I'm trying to finish so this would be a big help. Don't worry, I have all the weapons and costumes I need so we just need to beat the chapter.

My gamertag is the same here,

So let me know if you'd be down to help for this, thanks.

Dead Rising 3

Got to chapter 7 on coop on nightmare mode and both died and the last time we saved was at chapter 4 Back to chapter 4 again, Its much easier if your higher levels and have most of the blue prints for the weapons.
