From the creators of Duke Nukem 3D comes the one and only, truly authentic, expansion pak.

See two new enemies, and a new boss get their butts kicked by Duke's steel-toed boots and 10 other weapons
Smell steaming entrails as Duke's new Microwave Cannon fries and explodes those alien bastards
Hear aliens squeal as Duke aborts their entire race in one of two controversial new cut-scenes
Hear dozens of all-new one-liners from the man himself (Duke Talk)
Ultra-cool new feature allows playing multiplayer games against AI controlled computer opponents (up to 7 of them)
Other Duke-approved stuff: Duke Win95 themes, 5 Duke Screen savers, 6 Duke jigsaw puzzles and Image Carousel
