100 Invaders is a sub-dimensional game based on the classic Invaders, the first spaceship game in history. The objective is to shoot as precisely as possible and destroy all the invaders and their ghosts.There is no doubt that 100 Invaders is the right title for an action arcade game of this type. The graphics and sound are effective, although a little rudimentary, and the principle novelty is in its radical planning, as said before, because you have not only to destroy the enemy spaceships but also their ghosts. Ideal to pass a little time without too much effort.
