Space Cruiser

The player controls a spaceship who travels throughout space and defeats aliens. Compared to Taito's earlier Space Invaders, the game introduces a number of innovations, including a variety of different levels and enemies moving in different patterns. The player starts off intercepting and destroying an unidentified flying object followed by flying aliens. Multiple similar levels are bridged with different sequences such as navigating an asteroid belt and gaining power-ups at space stations. The game ends after the spaceship destroys the planet spawning the aliens.
