Baraduke (バラデューク Baradyūku), also known as Alien Sector in the western world, is a 2D scrolling science fiction shooter arcade video game that was released by Namco in 1985. It runs on Namco Pac-Land hardware but with a video system like that used in Metro-Cross and Dragon Buster.
The game is notable because Toby Masuyo, one of its main protagonists, predates by one year Samus Aran from Metroid as a human female playable character.
