GameBoy: ParodiusThis is mostly the parody of Gradius (Nemesis on some systems), with some flavor from other shoot em ups, like Twinbee. The series is available on numerous platforms. The game is a right to left scrolling shoot em up. You can choose from 4 different flying creatures, with different weapons. You must finish 7 stages, each having a boss at the end. You may start at either one, but must complete every level to advance to the final stage.
