Fighter Squadron: The Screamin' Demons over Europe is a Windows-based World War II themed combat flight simulator. The simulation player can man all the positions on WWII bombers such as the Boeing B-17 Flying Fortress, Avro Lancaster and Junkers Ju-88. In addition, other aircraft could be flown in the simulation including the Lockheed P-38 Lightning, North American P-51 Mustang, Supermarine Spitfire, DeHavilland Mosquito, Hawker Typhoon, Focke-Wulf FW-190 and the Messerschmitt Me-262. The simulation also features a fairly easy to use mission editor that players can use to create their own missions.
This updates the BasePack (which is still required) to v3.1 and renders v3, the Interim Basepack Update, and the BasePack Hi-Res Skin Pack obsolete. The only change from v3 is the removal of dashes and commas from the US squadron names. They caused problems in the Mission Editor.
