Summary: Shoot, attack and stave off the assault by defeating all the Invaders on the screen. After annihilating a battalion of Invaders and defeating the Boss, players move on to the next stage. But it’s "Game Over" if players lose all of their stock cannons!
Excerpt: They’re back. They never really left, though. The Space Invaders still haven’t given up attempts to wipe out the human race. It’s been decades since the war started, and it was almost finished in Space Invaders Extreme . Not happy ending, but a bitter, brutal one. Those little bastards really upped the ante that time; they descended to Earth like a swarm of pixilated locusts, spewing laser death and bullet showers upon the helpless population.
