This week? Time for another Mission to use alongside your Demo Kit. Below are the front and back of the Mission; you can also scroll to the bottom of the Downloads page and click on the last link (SHADOWRUN: CROSSFIRE DEMO KIT MISSION: Closing The Portal) to download the free PDF. (If you’ve not yet taken a look at the Shadowrun: Crossfire Demo Kit rules and print & play cards, you can find them at the bottom of that page as well.)
