DESCRIPTION

Invasion Fall has you playing the role of an alien who must prevent an invasion. Rockets launched from a rival planet are attempting to break through alien defenses, which consist of three rows of blue and white boxes covering the top of the screen.

A box is eliminated whenever a rocket makes contact with it, so you must maneuver the alien in coordination with the launched rockets and block them. When a rocket has been blocked, a defensive box appears at the point of contact and a point is awarded.

These extra boxes provide added defense from the invading rockets. Because the alien cannot move vertically, defensive boxes serve as expendable means of protection. The game ends once the rockets break through the upper three rows. ~ Matthew House, All Game Guide
