Long ago I used to play a game on one of the old consoles such as nes or megadrive or something like that and cant remember one of the games that i used to play and wanted to know cause want to play it! The game was a side view platform game like contra and the graphics wern't like childish style like mario or something. You would kill people with something (cant remember) but think you picked up numbers (or something like that) and once you got three numbers they created a combination to a certain robot weapon that would fly alongside you killing things while you continue to kill. There were levels such as the factory, carnival, underwater and other ones. If anyone knows what the hell im talking about please tell me, thanks
