TwinBee (????? TsuinB?) is a cartoon-themed vertical-scrolling shoot 'em up game. TwinBee can be played by up to 2-players simultaneously. The player takes control of a cartoon-like anthropomorphic spacecraft, with Player 1 taking control of TwinBee, the titular ship, while Player 2 controls WinBee. The game controls consists of an eight-way joystick and two buttons: one for shooting enemies in the air and the other for dropping bombs to ground enemies (similarly to Xevious).
