Invasion

Cosmic beings must invade the planet Sunset to settle before their own world is consumed by a cesspool in space. Your mission is to clear the planet's surface in each level before the resupply ships land. In each level, you will face three enemies that you must hit multiple times to eliminate them and clear the area, allowing the ships to land safely. As you advance, the enemies will become faster and more resistant to your bombs, and the enemy fleet will also appear blocking your way to the runway.

This Atari 2600 game challenges you to fight for the survival of your species, no matter the cost.
