There are games which feature a heavy degree of shooting but do not fall into this subgenre. Mega Man, Metroid, Ghosts 'n Goblins, Vectorman, Jazz Jackrabbit, Earthworm Jim, Cuphead, and Turrican are all platformers with a heavy focus on action and shooting, but unlike Contra or Metal Slug, platform jumping elements, as well as exploration and back-tracking, still figure prominently. Run-and-gun games are generally pure, and while they may have vehicular sequences or other changes in style, they stay focused on shooting throughout.[opinion]
