Official Alien Armageddon artwork

Duke Nukem: Alien Armageddon is a total conversion for Duke Nukem 3D: Atomic Edition. It was created by DukeBoss Productions and initially released on August 24th, 2018. The EDuke32 source port, which is included in the mod's ZIP file, is required to play it. The mod features a playable female character named Bombshell, new levels, new weapons, new sound effects, new graphics, new music, new enemies, new voice-overs, and new bosses. Duke Nukem: Alien Armageddon is meant to be a natural extension of Duke Nukem 3D and what it represents.


Duke Nukem: Alien Armageddon originated in January 2018. Sebabdukeboss20, an artist known for his erotic Duke Nukem 3D artwork, started working on making sprite variants of existing enemies after being inspired by the Project Brutality mod for Doom. He eventually started working on unique enemies based on Duke Nukem 3D and Duke Nukem Forever concept art. Deeperthought, a modder well-known for his Attrition (2010) and Duke Forces (2016) total conversions, was looking to get back into modding. Sebabdukeboss20 and Deeperthought started collaborating, eventually bringing others in. One day, Sebabdukeboss20 unveiled a Bombshell sprite sheet that gave Deeperthought the idea of creating an AI partner to make this mod unique. Duke Nukem: Alien Armageddon had a tentative release date of July 1st, 2018. The initial version was released in less than a year, a relatively short time compared to other total conversion mods.

After the first release, there was immediate requests for compatibility with expansions such as Duke it out in D.C. There was originally a quick patch to make it work, but eventually it became part of the Duke Nukem: Alien Armageddon canon. The levels were left intact but radically overhauled with newer and updated artwork. Some levels, such as Smithsonian Terror, were slightly reworked to be less confusing. Sebabdukeboss20 made a substantial effort to add lots of art to the Smithsonian so the player could explore it like a real museum.

Version 2.0, a major update, was released on February 16th, 2019 with many new features and fixes including an overhauled Duke it Out in D.C. episode and surprise Duke Caribbean: Life's a Beach episode.

Alien Armageddon 2

Version 2.1 was released on March 1st, 2019 and includes bug fixes, upscaled vanilla enemies, and an optional censored art patch for video streamers. Version 2.15 was released on March 17th, 2019 and included additional bug fixes, coding changes, and art and level updates.

Version 3.0 was released on March 6, 2020. It features a new episode called Space Gladiators with a pseudo style deathmatches similar to Unreal Tournament. It also features several new weapon and shield upgrades that can be purchased from collecting money from matches.

Version 4.0 was released on April 16, 2021 commemorating the 25th Anniversary of Duke Nukem 3d. It features War of Attrition mode which updates an older Duke mod gameplay mod. It also features several gameplay changes including a permanent upgrade vendor, new weapon and perk upgrades, completely redone vanilla enemies, savable slime babes, and several other improvements.

Veresion 4.5 was released on March 20, 2022. It features a new character of Wes Wolf (parody of Blade) in a short episode called Resistance taking place during Space Gladiators when Duke and Bombshell are off world. It also features more gameplay tweaks, a few new enemies, and several new voxels.

New features[]

Alien Armageddon includes several new features and modern gameplay updates.

This list comprises most of, but not all, the new features:

  • Selectable cooperative AI. Bombshell can be used with Duke or individually in any level.

When the partner's health is low, you can teleport them to your location and heal them using some of your own health. Bombshell also has unique voice acting and toilet interactions. In co-op, Duke's AI uses a shotgun while Bombshell uses an M4. Their costumes can also be switched (as well as color palette in 2.0).

Duke Nukem: Alien Armageddon currently has 4 unique episodes as of version 3.0.

Episode 4.5: Duke Caribbean: Life's a Beach (2.0)[]

Caribbean expansion re-purposed as a prequel to New Invasion. The levels are enhanced but do not contain the [playful] cosmetic weapon and enemy changes. This episode was kept as a secret for release. It was adapted late into 2.0's development.

Earth is suddenly attacked again by aliens, but had help on the inside. Duke Nukem and his partner Bombshell go to find it who it is.

Episode 6: Duke it Out in D.C. (2.0)[]

Duke and Bombshell are transported to a different planet and forced to fight in alien gladiator deathmatches for the amusement of Emperor Braccus, who promised to leave Earth alone. They have to fight their way through several deathmatches with varying unique enemies. After each arena, Duke and Shelly are returned to the Gladitorium where they can explore and talk to others and upgrade their arsenal using money from the matches. Will Duke and Shelly work their way to the top of the board and win their freedom? Finishing all 3 ancient secrets will unlock a weapon upgrade HUD that can be used in any map/episode.

(Episodes 1, 2, 3, and 4 are the same as those found in Duke Nukem 3D: Atomic Edition but now contain randomly placed enemies and cutscenes.)
