Alien World Order is the fifth and final episode in Duke Nukem 3D: 20th Anniversary World Tour. It is not available in the original version of Duke Nukem 3D or the Atomic Edition release of the game. Each mission is set in a different country around the world. From Amsterdam, Egypt, England, and all the way back to Hollywood itself to name a few levels.
This episode is also notable for featuring more than one boss enemy. All original bosses make an appearance throughout the levels, and for the first time - killing them will not end the level.
