空牙/ Vapor Trail

Vapor Trail is a shoot-'em-up that features 2 players controlling the jet fighters simultaneously for battle across numerous levels.

Unidentified forces have taken over New York City, and a network of airborne military fleet is manned to reclaim the city. You play as one of three ships in the network: Sliph, a medium-speed attacker/fighter, Valkyrie, a low-speed attacker, and Seylen, a high-speed fighter. A second player can man a second ship for two-player combat.
