Sorry about that but there is one more thing that is more scarier than doom 3 and that is ghostopedia.It was started by Mr akash and mr Shravan.It covers up darker ascpects of ghosts and ghouls when wikipedia refused to pick it up.
It is not yet online but it will be soon for more information contact thegreatakash@gmail.com
