I love games. I love editing games. I'm a shitty editor. Will help where needed.
After an insatiable appetite for all things covenant got the better of me, I made a map that was at least made up 50% of asteroid fields, and quickly made a boarding group of 2 - then 4- then 6 Hacyon Refit capitals to cap whatever covenant vessels there were...which came to about 11 cruisers, 10 pickets (Those were cannon fodder if I couldn't cap all 6 ships at once), and 30+ frigates.
With out much anti-air support, they didn't really do all that well ...
