Description:
This is not your father's Space Invaders. These 3-D alien troops now come with enhanced firepower, special effects, and even a two-player mode (Game Link cable required). The game offers 100 levels of basic dodge-and-shoot gameplay, which now takes place in interstellar locales. Your new arsenal includes an infrared laser beam, flamethrowers, and a neutron blast, plus bonus power-ups and special weapons unique to each world. And if you're inclined to think that the original was the best game ever, that version is included here, too.
