Duke Nukem Wiki

The Invasion of Trequonia is a standalone total conversion for Duke Nukem 3D. It was created by Cedric "Zaxtor Znort" Lutes and was initially released as version 1 on August 20th, 2017. The Invasion of Trequonia does not require Duke Nukem 3D or Duke Nukem 3D: Atomic Edition to work, though the EDuke32 source port is required and comes with the mod in the .zip file. The Invasion of Trequonia contains new levels, new graphics, a new sprite for the player's character (Skyhv Knawvkiov, a pantheist anthropomorphic wolverine), new enemies, new weapons, new cutscenes, new bosses, new music, new sound effects, and new voice-overs. A patch (called "trequoniav2" as a .zip file), which updated the mod to version 2, fixed multiple bugs, contained three new levels (ANWR Route 2, Control Base Route 2, and Deep Arctic Cave), level modifications, and new difficulty levels, was released on February 8th, 2018.


2,500,000 light years away from the Milky Way galaxy, Trequonia, an artificially made planet that is the size of the Earth's moon, has been invaded by aliens and soon begins to orbit planet Earth. Skyhv Knawvkiov, who lives in the Arctic National Wildlife Refuge (ANWR) in Alaska, fears for the safety of Earth, so he goes to destroy Trequonia.


The Invasion of Trequonia started development in early 2010; the mod was announced on April 26th of the same year. The Invasion of Trequonia was finished after over half a decade of development.
