Invader

Earth has once again faced an alien threat, this time from the Invaders, a new wave of extraterrestrial invaders. The technology recovered during the 1978 invasion has been used to create a new Tank, a powerful machine that will aid in the fight against these intergalactic visitors.

As players progress through the Solar System, from Pluto to Earth, they will encounter various types of Invaders, including common and less common ones. Special power-ups can be obtained by shooting four of the same type of Invader in a row. Additionally, Mother Ships will appear above the action, providing further challenges and opportunities for advancement.
