Foregoing the storyline, as it's a DOOM-like game. It doesn't need a story, other than demons, big guns, and lots of firepower.
This is my new and improved main menu, I might change the background image, because it's the same one I used in DOOM: Legions of Hell, and it probably wouldn't go well with the new game, and it'll seem like the old one. I have perfected the transparency for the skull, and even ingame (which is really nice).
