Classic Game Room reviews OZMA WARS for PS3 & PSP from SNK Playmore, a 1979 space shooter available as a Playstation Mini from Playstation Network. Break out the old black and white TV because it's time for Ozma Wars... which means it's time for Space Invaders because even though Ozma Wars is one of the first games to include "different wave" style attacks, it pales in comparison to Taito's mighty Space Invaders.
