Kuhga - Operation Code: "Vapor Trail" (空牙) [*1] and usually simply referred to as Vapor Trail, is a 1989 science fiction shoot 'em up arcade video game developed and published by Data East. It was released outside of Japan as Vapor Trail: Hyper Offense Formation.
The game features 2 players controlling advanced jet fighters simultaneously for battle across numerous levels. There are 3 types of jets varying from different classes of speeds and firepower. The XF/AV-01 Silph is the midrange plane with the most balance, while the slow XAV-02 Valkyrie carries the most firepower, and the experimental XFV-03 Seylen jet is capable of flying at the highest Mach speed.
Kuhga was later ported to the Sega Mega Drive/Sega Genesis in 1991 by Telenet Japan. This port was very accurate to the arcade counterpart despite much stricter hardware and color limitations.
Vapor Trail was followed by two shooter sequels: the mecha shooter game Wolf Fang and another aircraft shooter called Skull Fang (Kuhga Gaiden).
[*1]: Danbooru's Romanization of 空牙 is "Kuuga", but the game screenshot spells it "KUHGA".
