I just saw this: http://www.macgamer.com/news/images/826.gif
It's the picture that MacGamer.com used for a story describing "Word of a flick based on DOOM (id software's gory first person shooter)". (http://www.macgamer.com/news/item.php?id=7918)
Now, is it just me, or does that picture -- minus the HUD, weapon, and menu bar/title bar -- look quite similar to something in Marathon 1? The textures especially: I don't remember what the textures looked like exactly, but I do remember enough to make me wonder (the hexagons and the blue tiles, specifically). And then there's what looks like the charred remains of some hapless Pfhor.
Now, I've neither played Doom nor seen much of it at all, so this may indeed be authentic. Mebbe it's just convergence of looks of the games (or at least this one room).
Anyone have a better scoop?
