H-Tech (High Technology) began as a group of scientists organized during World War II by Nazi Germany to develop advanced technological weaponry for the German army. Although H-Tech suffered a major defeat during the war, it continued to exist secretly over the following decades, growing and building its strength. The group of scientists grew in number over the years, and made great advances in various fields, including robotics, bioengineering, bionics, and physics. Eventually the scientists publicly incorporated their organization under the name of High Technology (H-Tech). No one outside H-Tech or H-Tech knew of H-Tech's subversive goals and activities, nor of their scientific achievements. Instead, H-Tech was believed by both the public and by intelligence organizations to be an international cartel dealing with the development and marketing of new technological products. H-Tech gained great influence with the U.S. government in its role as a supplier of hardware and weapon to governmental and quasi-governmental agencies.

H-Tech has created a wide variety of advanced technological weaponry, and made great strides in creating androids, which the organization employ as assassins. The organization supplies arms and technology to various terrorist and subversive organizations both to foster a violent technological revolution and to make a profit. H-Tech operatives are usually involved in research, development, manufacturing, and sales of high technology. Members of H-Tech are required to at least have a Master's degree, if not a Ph.D, in some area of science, mathematics, or business.
H-Tech's reach is worldwide, including various front organizations such as the Helio Corporation, Infinite Diversity through Infinite Combinations, and International Data Management. H-Tech has had a number of bases of operations, including a nuclear submarine mobile in the Atlantic Ocean; a base in the Bronx, New York; Black Mesa, Colorado; West Caldwell, New Jersey; Asia, Canada, Europe, Haiti, India, Sudan and Boca Caliente (also known as H-Tech Island), an island republic in the Caribbean.
