AI generates new Doom levels for humans to play

One of the longest-lasting and most successful video-game franchises is the Doom series, launched in 1993 and still going strong with over 10 million copies sold. The game is a first-person shooter in which a space marine battles to survive against various demons and zombies. The game is notable because it pioneered 3-D graphics for PCs running MS-DOS, introduced networked multiplay, and even allowed players to create their own game levels. Indeed, large numbers of Doom levels--both official and player-created--are now freely available online, forming a formidable corpus for study and research. And that raises an interesting possibility.
