From publisher blurb:
Is the chaos spreading or concentrating? Either way, it’s increasing, and shadowrunners are sure to be caught in the middle of it. People have been pouring a lot of energy into the core of Chicago, and a final reckoning is about to take place. It’s up to the runners to decide where the pain hits.
Final Countdown is the grand finale of the Chicago series of Shadowrun Missions. After four seasons of Missions, the climax is here, and it’s going to be a doozy. Buckle up, hold on, and try to survive the ride!
