Galaxia

Alien forces have arrived, and they are set on destroying you. It's just your sole spaceship up against their waves.... Galaxia is yet another clone of Galaxian, where the player shoots down endless waves of alien craft formations for high score. On each round, a bunch of different airborne enemy sprites will pop up on a fixed playfield and engage in shooting and diving maneuvers against you. Your ship resides on the bottom part of the screen and can only move horizontally and shoot straight up with its gun, taking them down, each one adding points to your score. When a wave is cleared, a new one will appear. Contact with enemy fire or the aliens themselves will deprive you of a life. When all lives are lost, the game will end and a new session can be initiated, with your score back to zero.
