Warfare - Fully Powered— West-Tek slogan

The West Tek Corporation, also referred to as West-Tek or West Tech, was a major United States defense contractor and research corporation, involved in strategic defense projects of the Department of Defense, such as Power Armor and FEV research.[1]


West Tek was founded in 2002 and established the Advanced Weapons and Biomedical Sciences Research division.[2] Its early projects included the X277 "Viper" Magnetic Rail Cannon. Although powerful, the cost of fielding such a weapon on a mass scale were considered too extreme and the project was shelved in 2044.[3]

West Tek was the first to develop a Power Armor frame and the first practical series of Power Armor, the T-45 model D.[4] The first mechanized infantry units equipped with T-45d Power Armor were deployed to the Alaskan front, and although lacking in mobility, they were effective in stemming the Chinese onslaught, thanks to their ability to carry heavy ordinance into battle with ease.[5] In 2069, it was the single largest defense contractor for the United States government, with its biggest contract being the T-51 Power Armor.[2]

In 2073, West Tek was contracted to develop a general immunization agent against the New Plague and biochemical weapons used by China. This generalized immunity virion was designated the Pan-Immunity Virion Project and formed on September 15.[6] This attracted the attention of West Tek's military liaison, Major Barnett, who immediately ordered further experiments in that direction in March, 2075. Subsequent successful experimentation on flatworms and small mammals confirmed the viability of PVP as an evolutionary mutagen, now designated the Forced Evolutionary Virus.[7]

The last attempt to continue the PVP line of experimentation was the Greenhouse Initiative, which attempted to use the mutagenic potential of PVP to create edible plants and vegetation that could greatly increase food production and combat the shortages that led to the food riots rocking the country.[8] The town of Huntersville was selected as the test site, resulting in an economic boom.[9] Although the company would purchase test rights from local farmers as late as December 2075, the project was at an end.[10]

West Tek's progress was taken over by the United States Government and the development of FEV continued, with support from the military's own advisory teams.[11] New genetic sequences were spliced into FEV, gradually turning it into a shifting-absorptive virus that had little in common with the original Pan-Immunity Virion. It resulted in increased intelligence, dexterity, muscle mass, and resiliency to pathogens and cancer.[6][7]

The Greenhouse Initiative was scrapped and the researchers reassigned to other projects[8] as West Tek decided to use its Appalachian branch to focus on experimenting with FEV to determine its practical limits, with Huntersville as proving grounds for low-level FEV exposure experiments and source of test subjects.[12] The Advanced Weapons and Laser Development divisions completed their own projects by the end of the year, resulting in the T-51 Power Armor being put into production after testing and further iteration by the Army Corps of Engineers at Fort Strong.[13]

In January 2077, the FEV project was nearing completion. All Californian FEV research assets to the newly constructed Mariposa Military Base, including a significant portion of West Tek's research staff, ignoring recommendations against human testing from the personnel.[6] In Appalachia, experiments created stable mutations that would become known as the snallygaster[14] and the Grafton Monster,[15][16] By the time of the Great War, most of West Tek's personnel in California were already dead, killed by Roger Maxson's forces in response to the research they discovered taking place there.[17]


Founded decades earlier than the other major corporations of the pre-War era, West-Tek competed for market share in the advanced weapons and biomedical sciences industries. They were immensely successful in both fields, relying primarily on massive government and military contracts to drive their business.

Advanced weapons projects ranged from simple firearms, to the X277 “Viper” portable rail cannon. However, by far their most successful project was the T-51 Power Armor. This infantry enhancer drove profits starting in 2062 until seeing widespread and successful deployment across the battlespace of the Sino-American War. Early models, especially the earlier T-45 line, suffered from mediocre mobility and protection, but later developments produced a truly formidable weapon. As the war continued and choked resources, other, lighter, less expensive variants emerged.
In the early 2070s, with the legacy of the New Plague and the threat of Chinese bioweapons looming, West-Tek landed a contract to develop a wide-spectrum immunization to protect American citizens. Under the leadership of Division Director Nick Davis, this Pan-Immunity Virion Project met with strong initial success. Early doses produced effective immunity to a wide variety of infectious agents. Some side effects, especially increased muscle mass, spawned the research that would ultimately become the Forced Evolutionary Virus (see sidebar).
Escaping mutants from ongoing FEV testing combined with the nuclear strikes to turn most West-Tek facilities into nightmare death traps during the first hours and days of the post-war era. Ravaged by threats from within and without, the company as an entity became one more casualty of the nuclear exchange.

After the War
By far the largest shadow cast by West-Tek into the post-War era is the T-51 Power Armor and its variant models. They were produced in such quantities during conventional warfare prior to the nuclear exchange, they remain relatively common. They continue to empower any factions with access to them, often providing a decisive advantage in any armed conflict.
Legacies of their other projects also linger, ranging from advanced weapons in the hands of survivors, to any number of humanoid and animal mutations from FEV that roam and ravage the landscape.

Two West-Tek facilities loom large in their immediate regions. A surviving research center in Savage Divide, Appalachia, served to further final stages of the Pan-Immunity Virion project, and still contains several working labs and workshops, as well as scattered tools and supplies. Surviving mutants from human and animal testing haunt the grounds. Far underground, near Vault 13 in New California, is another facility known only as “The Glow,” said to be a ferociously guarded holding cell for projects not quite finished when everything came to a halt.
