Hargreave-Rasch Biomedical is a company existing during and long before the Crysis 2 main storyline. As its name suggests, it is a biomedical company that was founded by Jacob Hargreave (death 2023) and Karl Ernst Rasch (alive as of August 2023).
The Company was founded mainly in order to serve as the front stage of what Crynet, the daughter company, was doing. Through the company, Jacob Hargreave and Karl Rasch developed the Nanosuit and Nanosuit 2 in order to face the impending Ceph invasion. Hargreave in particular knew about the invasion and was planning to wear the nanosuit himself to face the Ceph but was rendered inable due to age.
