The Viper King Autopsy is a research project added to XCOM 2 through the Alien Hunters DLC.

In-Game DescriptionEdit


Although clearly reminiscent of the known Viper species we encounter with some regularity, this specimen is unique for a number of reasons, not the least of which is its gender, this may be the only male Viper ever reported. It may be possible to repurpose some facet of its biology for our armor development programs.

Autopsy Commentary Edit

Although it had been years since I conducted my last autopsy, I found the process returned to me quite naturally. This subject was perhaps less intimidating because of its similarities to the varying reptile species found naturally on the Earth. Because of extensive cyrogentic modifications to the subject's chromosomes, this could very well be the only male variant in the entire species.

Project ReportEdit

Codename: Scorpion

Having carefully studied what remains of Dr. Vahlen's personal research reports, I've slowly come to understand the depths of her intellectual curiosity and the degree to which she was consumed by her ambition. By reversing key changes to the Viper's genetic structure, traits intentionally suppressed by the aliens, she created this, subject "Gamma" - the Viper "King."

The idea of a Viper patriarch is in itself intriguing, considering there have been no previous sightings of any male members of the species. Vahlen theorized this may have been an intentional form of population control, the Elders' having restricted their subordinate species ability to breed. Having seen the apparent nesting site created by Gamma and the discovery of egg clutches (none of which were left viable for sampling), I can say with some confidence that creature did immediately set out to pursue the natural instincts that had long been restrained through genetic tampering.

As yet I have no explanation as to how the Viper's venom glands were effected in such a way as to change their form and function so dramatically; further study will be necessary, but I've promised to allow some of Gamma's remains to be used in a new conceptual armor design. R.Tygan.
