The leaked prototype, which is available on Archive.org, includes multiple demo files that can be accessed through the in-game console. It is not clear how the prototype became available online. Some speculate that a former 3D Realms employee may be the source of both the Prey and Duke Nukem Forever leaks. The leak has generated excitement among fans of classic first-person shooters, with much expressing curiosity about the early versions of gameplay elements that appeared in the 2006 release of Prey.
