FASA
FASA Corporation is an American publisher of and Shadowrun and other games including BattleTech between 1980 and 2001.
In Shadowrun, a tactical nuclear device was detonated near FASA's offices at 1100 West Cermak Road in Chicago, Illinois.
The BattleTech and Shadowrun properties were sold to WizKids, who in turn licensed their publication to FanPro LLC.
FASA Corporation has since returned and is making Earthdawn again.
