Simon and Schuster, the company that published the original Doom novels, has recently released a new Doom novel, apparently set in the Doom 3 universe. Doom 3: Worlds on Fire was released at the end of last month in paperback only. The author, Matthew Costello, wrote the scripts for Doom 3 and its expansion pack, Resurrection of Evil.
