Thanks @Austinkos!
We're all really enjoying it, a couple of the other guys were on a bit of a
40K downer with the utter rules bloat of 7th but I'm generally on top of most of it so decided to try to re-invigorate them with the campaign. I've always loved making up new rules and scenarios (see the rest of my video battle reports - Teamclueless40K) and John makes some really awesome terrain so the campaign was born.
I planned out the basic story before hand for the five missions then we all discussed it and made some tweeks and such, so far it's been a roaring success with everyone having great fun in all the games with all players having stuff to play for even when they are nearly down and out.
I've almost finished writing the final mission so hopefully we'll get to play in a couple of weeks
