So for a future doom game, I was thinking it would take place a couple hundred years later after the second Doom 3 game. In this game, there are cities on Mars and people living up there. The Union Aerospace Corporation is gone, and parts of Europe and the United States run opporations up there. The main character either is or isn't a descedent of the Doom Guy from the first Doom 3 game. But in this game, Hell does get unleashed on Mars and Satan does make an appearance. But in this game, like the Modern Warfare games, you would play as two characters to defeat the Demonic Invasion from Hell. Now I did write a short story of it already, but isn't an official book of course. The game would be called Doom: Nightmare Asylum. That's all I can remember from what I wrote, but I still think it would be cool though.
