Alien Sector

Alien Sector (Baraduke in Japan and Europe) is an action shooter game where the player takes control of a spacewoman (player 1 is Kissy and player 2 is Takky) moving around in a low-gravity environment with the help of a jet pack, as they investigate the once-peaceful Planet Paccet, which has been taken over by aliens known as Octy.

The game consists of eight stages, each stage is split up into six floors, with five regular floors and a boss floor. In the first four floors in each stage, the player must clear the floor of Octy, then they can exit the level through a chute located at the outside walls of the level. In the second last floor, there are no Octy but lots of capsules, which can hold one of four things: a yellow coin object which gives the player 100 points, a ray gun that increases gun level by one, a Paccet, which can earn you extra shield in the end-of-floor bonus games or the Bagan, which is a Pac-Man-like creature that will attack the player.
