Invaders

Invaders is a variant of Space Invaders. It works like any other game of its kind with the player moving a laser base along the bottom of the screen while shooting at an alien formation made up of five rows of aliens that progressively get closer to the player. Different aliens are worth different point values and when reaching 2000 points an extra base is granted to the player. Like in the arcade game barriers offer some protection and an UFO will at times pass by at the top of the screen. The player has three lives.
