During early March 1999, ATI leaked the internal hardware vendor (IHV) copy of the game, which unveiled to the public in Macworld Conference & Expo at Moscone Center in January and Makuhari Messe in February by Steve Jobs (CEO of Apple Inc. at the time when it unveiled). This was a functional version of the engine with a textured level and working guns. The IHV contained most of the weapons (excepting the Gauntlet) that would make it into the final game although most were not fully modeled; a chainsaw and grappling hook were also in the IHV but did not make it into the final release. Many of the sounds that would make it into the final release were also included.
