After putting an end to an alien threat in Duke Nukem II, Duke returns to Earth only to find another extraterrestrial invasion underway. Armed with his wits and an extensive arsenal of weaponry, Duke will travel through various locations both on Earth and in its orbit, and even on the Moon in order to push the alien invaders back.

Instruction / comment

The shareware version contains the entire first episode of the game, L.A. Meltdown. There are five regular levels and one secret level. NOTE: This game can be played directly in Windows using a source port (see the links section below). If the game runs too slow in the browser, press F5 to switch to low detail, which will speed it up.
