The Alien Queen Sentry, also known in the online community as the Mini Alien Queen or Alien Princess, is a scrapped enemy that first appeared in the game files for Duke Nukem 3D: Atomic Edition and then appeared again in an updated form in the game files for Duke Nukem 3D: 20th Anniversary World Tour. The Alien Queen Sentry is a smaller, weaker version of the Alien Queen.
Atomic Edition[edit | edit source]
In the Atomic Edition, a sprite and code exists for the Alien Queen Sentry, though the enemy never appears in the game. However, the enemy can still be artificially inserted into the game using a map editing utility; placing the enemy sprite anywhere in a level and changing the sprite palette will produce a fully functional enemy. In the Atomic Edition, the Alien Queen Sentry has no preset palette, making its choice of color largely arbitrary. It uses the same sprite as the Alien Queen, but it has only 1 health. It mimics every aspect of the Alien Queen's behavior, including triggering a one-liner from Duke when he approaches. Killing the Alien Queen Sentry will end the level, and the cutscene from The Queen will play.
20th Anniversary Edition[edit | edit source]
In the 20th Anniversary Edition, the Alien Queen Sentry's code was fully updated like the Overlord Sentry's and Cycloid Sentry's, but it still does not appear anywhere in the game. In addition, approaching the Alien Queen Sentry will still trigger the one-liner that plays when Duke discovers the Alien Queen.
Nuclear Showdown[edit | edit source]
In the online Duke Nukem community, the Alien Queen Sentry is possibly best known for its appearance in Nuclear Showdown, a popular total conversion for Duke Nukem 3D: Atomic Edition. In the mod, the Alien Queen Sentry uses a red palette (pictured above) and spawns Protozoid Slimers.
