Catalyst Game Labs is running a contest wherein you could get your mission added as part of the official organized play for the kit.
From the announcement:
Shadowrun: Crossfire is in the wilds, being played and enjoyed by thousands of gamers. Not only has it had great critical acclaim, but it’s rapidly selling out of its first print run; we’re already lining up a second printing, and the first Mission Pack!
With all of that excitement in mind—alongside the wonderful campaign nature of the game in earned karma and stickers—we’re announcing a Create a Shadowrun: Crossfire Mission Contest.
If you love the Shadowrun world and Shadowrun: Crossfire and have a story you’d like to tell, here’s your chance to get in on this action! Design your own mission to have a chance to win!
