Well I know someone on this post said that there is only 8 stages, but if you watch the 22mb vid that was posted on this trend. You will see as the Dyrl music kicks in and before they show the sdf-1 you will see a menu, and it says stage 12. Then as you watch vid more you see a another menu and says stage 8. So this almost confirms that there is more then 8 stages. So, I think that there is only 8 story stages and maybe more extra stages that you can play that do not tie in with story mode. Like Isamu/guld, Max/Mila, and the Movie ending. Well that is my 2 cents.
