Not posted here before but I see you are an active community and hope this will interest you.
I wanted a new mission set for Space Crusade using requiring only what comes in the original box and couldn't find one on-line so a wrote one! I hope that this will be useful and interesting for others but also wanted some feedback / suggestions for enhancement.
I wanted to make it fairly difficult for the Marines but am not sure if I've got the balance right with reinforcements mission objectives etc. Also I am no good with 40K fluff so I'm sure the story /theme could be vastly enhanced
The only issue I have with it is that you didn't give the campaign a cool name. Like, I can say we're playing the Renegade Campaign from White Dwarf- but I don't have a quick shorthand for your campaign.
