Stinger is a vertical/side-scrolling shoot-'em-up game for the NES and Famicom Disk System. In Japan, it was released as Moero TwinBee: Cinnamon Hakase o Sukue! (JP). The game was later released on the Wii Virtual Console in Japan and in North America on the Wii U Virtual Console.
Unlike the original TwinBee, which only featured vertical-scrolling stages, Stinger adds side-scrolling stages as well. There are seven stages in the game. Stage 1, 3, and 7 are side-scrolling, while the rest are vertical-scrolling.
The controls remain the same between the two styles of gameplay, with the only difference being that in the side-scrolling segments, the A button shoots hearts over the ship instead of dropping bombs into the ground like the vertical-scrolling segments, which helps the player keep the power-up bells afloat in the side-scrolling stages.
There are six types of bells: yellow bells give the player bonus points as usual, blue increases the ship's speed; white upgrades the player's gun into a twin cannon; pink gives the player a laser beam cannon; the flashing pink/white bell gives the player's ship mirror options for added firepower; and the flashing blue/white bell will surround the player's ship with a barrier for extra protection from enemy fire.
Other power-ups are acquireable by destroying ground enemies such as a moon item and star item which gives the player's ship a three-way shot and a five-way shot respectively. If two players are playing the game, they can align their ship together to turn their gun into a ripple laser.
Stinger, the NES version, supports up to two players, as it predated the release of multiplayer adapters such as the Four Score and Satellite. The second player controls GwinBee instead of WinBee, who is absent from this version. The NES version lacks the opening and ending screen showing the three grandchildren of Dr. Cinnamon, as well as the selectable difficulty settings at the title menu.
