Former Gearbox employee Gregor Punchatz uploaded a demo reel video and in it you can find Duke Begins footage at 5:56 below; this is a CGI “proof of concept” from the mid-to-late 2000s. Duke Begins was a cancelled video game proposed by developer Gearbox Software. Few details have been shared since its reveal in 2009, though its title carries the implication of a Duke Nukem origin story, illustrating how Duke became the person he is in chronologically later games.
