what do you mean about "vertical scroll"? 3dgs is a 3D engine. so, if you want to simualate simple 2D scrolling game you have to work a little (plan you level, positioning the camera, make right movement scripts and so on).
If you want to scroll a panel, you can do it too (make panels as entities, place your camera above and apply proper script to move the camera, for example)
Or is you question about something else?
