TwinBee

TwinBee can be played by up to two players simultaneously. The player controls a cartoon-like anthropomorphic spacecraft, with Player 1 taking control of TwinBee, the titular ship, while Player 2 controls WinBee. The game control 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).

The player's primary power-ups are bells that can be uncovered by shooting at the floating clouds where they're hidden. If the player continues shooting the bell after it appears, it will change into one of four other colors: the regular yellow bells only grant bonus points, the white bell will upgrade the player's gun into a twin cannon, the blue bell increases the player's speed (for up to five speed levels), the green bell will allow the player to create image copies of its ship for additional firepower, and the red bell will provide the player's ship a barrier that allows it to sustain more damage. The green and red bells cannot be combined. Other power-ups can also be retrieved from ground enemies such as an alternate bell that gives the player's ship a three-way gun, a star which eliminates all on-screen enemies.

In Japan, Game Machine listed TwinBee as the third most successful table arcade unit of March 1985.

The version of Twinbee for Nintendo 3DS received a total of 68/100 on Metacritic, which is mixed to positive, with an average user score of 7.3.

In 2022, Konami organised Konami Action & Shooting Contest to encourage indie developers to make games based on some of its classic series, including TwinBee. Hosted by the Shueisha Game Creator's Camp and Tokyo Game Show, Ken Niimura won the rights from Konami to develop the game through the competition; his team's proposal was named TwinBee Loop!: The Mystery of the Planet of Light and Darkness!!.
