The NEXUS, and especially Division V, operates a varied mix of technology. Some of these are proprietary developments, but others are hijacked alien technology.
The devices are researched and further developed in an own research facility. Xenos knowledge is required to operate the alien devices.
The NEXUS had been researching a powerful AI for years, which was supposed to be used for the administration of the station of Division V. The AI was not yet ready. Stupidly, Argen let it escape on a laptop shortly before its completion. The encounter with the AI and Argen was to be the players' first experience with the NEXUS.
