The first video footage of the game was released at E3 1998, but director George Broussard was not happy with this build of the game and scrapped it soon afterward to focus on a new build of the game in the new, more powerful Unreal engine, the reason being that the Quake 2 engine was unable to render the vast areas around the Hoover Dam. During this time, Duke Nukem Forever was meant to be released early in 1998 and serve as a stopgap while another team at 3D Realms was developing a more powerful engine, intended for its next game: Prey. The announcement claimed the game would be based on the Quake 2 engine, but the team did not actually receive the Quake 2 engine code until November: all screenshots posted prior to this were bullshots made in the Quake 1 engine instead, which 3D Realms received the previous January. The game began development almost immediately after the release of Duke Nukem 3D in 1996, it was first announced on April 28, 1997, and the first official screenshots were sent out in August and September.
