the fact that the game box will have dual cover artwork, so if the big green octopus thingy is not your cuppa tea there is the flip side art of a pilot's helmet. Take your pick I guess!
If that's not enough they also obtained a whole slew of new screenshots, showing the newly revised hud amongst other improvements. You can check out the rest of the screens over at Sega Portal. Safe to say this game is looking rather good. I mean look at this mean fella of a boss!
