Galaxians

Galaxians is a classic arcade game developed by Namco. In this space shooter, you control a spaceship as it navigates through waves of alien enemies on a number of planets. The objective is to destroy these aliens while avoiding their laser fire and missiles.

The gameplay involves using your ship's cannon to blast enemy ships, which will then drop bombs that can destroy other ships if they get too close. As you progress through the levels, new types of enemies are introduced, including larger and more powerful ones.
