Nemesis Game Boy review. http://www.ClassicGameRoom.com Shop CGR shirts & hats! http://www.CGRstore.com Classic Game Room reviews NEMESIS from Ultra (Konami) released in 1990 for the Nintendo Game Boy! Nemesis is like a condensed version of Gradius with the enemies, gameplay and music that fans of Konami's awesome space ship shooter series know and love. Blast enemies, collect power ups and options but beware of crashing into walls or catching a laser beam, it's NEMESIS!!!
