Vapor Trail: Hyper Offence Formation (known in Japan as Kuhga - Operation Code Vapor Trail) is a shooter video game created in 1989 by Data East. It is commonly referred to as just Vapor Trail and was ported to the Sega Genesis in 1991.
A Special Forces Air Unit is called in to attack DAGGER and cripple their strongest defenses and headquarters in New York. Until then, the city remains silent.
Every jet is equipped with a roll device that allows them to kamikaze safely into other jets. The roll must be re-charged after every use.
Players also have the choice to pick-up the S-Unit, a weapon attachment that empowers the jet's firing no matter what weapon is picked-up previously and every jet's S-Unit attack differs from the others.
Silph S-Unit: Fires diagonal wave shots in a V formation.
Valkyrie's S-Unit: Fires rapid-fire flame blasts in a straight direction.
Seylen's S-Unit: Fires an array of arrow-head shots with four firing from the front, two firing from the sides and front and two firing from behind.
Once the S-Unit is equipped, the player cannot use their previous weapons unless the S-Unit is detonated. Detonating the S-Unit does not harm the player, but it does harm the enemy as the unit will detonate in a large and powerful explosion.
This port was also featured on the game show Nick Arcade, in the Video Challenge portion of the show.
