Bogey Dead 6 (released in Japan as "Sidewinder" and in Europe as "Raging Skies") is a 1996 flight simulation video game developed by Pegasus Japan and Bit Town, and published by Asmik Ace Entertainment in Japan and Sony Computer Entertainment in other regions. The game features six real fighter planes: the F-4E, F-14D, F-15E, F-16C, F/A-18E and the F-22 Raptor. The game is played from the perspective of an ace pilot for the United States Air Force. The objective is to protect the United States from communist invasion, enemy involvement and terrorism. The game is very similar to the Ace Combat series. "Bogey Dead 6" is jet pilot jargon meaning "unidentified jet directly behind you."
