Twin Cobra 2 / Kyukyoku Tiger II

Twin Cobra II is a vertically scrolling shooter from Toaplan/Taito
The game is the sequel to Twin Cobra and was in development by Toaplan until Takumi took over, completed the game and Taito published it on their F3 System Board Hardware.
The Gameplay is like Twin Cobra: A shoot-em-up where players fly helicopters and fire at air and ground targets. Collect power-ups (green, blue, or red) for better fire power. Fight a 'boss' enemy at the end of each stage.
