Need help with Friends with Benefits achievement

[Broadbandmink]

Alright so here's the story. I've got 8 chapters left before I nail this one. I've confirmed every chapter from the start (including the training segment) up until Hive: No Turning Back, so I'll start from there. I did the final chapters years ago but the details are a little fuzzy by now so I'll run through those again just to be sure. Long story short, I'm wondering if anyone has got the time and patience to help me with this one?

If interested, Gamertag is Broadbandmink.

I'm online as of present.

Seems like I just signed in a second controller to play Dom and just kinda drug him from checkpoint to checkpoint. Sometimes you might have to put him in a safe place, but for the most part he will catch up as Marcus makes it to the next checkpoint.
