just like how you can get the flawless strike achievement by joining a strike seconds before the boss is killed, you can do the same in the VOG. I think Cody et al are trying to do it the right way and recording it.

I've heard from multiple sources that you cannot get the achievement in VoG if even a single person goes to orbit and comes back.
