The Library of Congress believes its found the source code to a never-released version of handheld game Duke Nukem: Critical Mass, unearthed from a trove of games submitted for copyright registration. It was originally supposed to be the start of a new trilogy, but it was released to terrible reviews, and its big brother Duke Nukem Forever didnt do much better. Gibson is still trying to reconstruct the game, but hes found game music and even pieced together a basic 3D model of Duke in a jetpack. Every work is automatically granted copyright in America, but in order to sue for damages, authors have to officially register with the Library of Congress, sending copies of their book, game, movie, or other project to be examined and potentially held in perpetuity.
