Rex Research Institute is a fictional organization in Counter-Strike Online.
The Rex Research Institute is an organization of doctors and scientists who were creating various types of medicine in an attempt to prolong life. Gradually, they changed their objective into trying to find a way to make humans immortal. Due to their continuous experiments on living things, their plans backfired and had instead created a dangerous virus, dubbed the Rex Virus. This caused humans to turn into the undead, the zombies. The zombies managed to escape from the lab, during Chaos chapter, and started infecting the others. This was also the place where Jennifer was captured and kept alive as a human experimental subject.
There are several maps showing this institute:
Terrorists threaten to destroy the lab for political purposes. (managed to destroy it insignificantly)
Counter-Terrorists were dispatched by the government to engage the Terrorists that were escaping from the institute after the bombing in the main lab. There are no signs of any zombies yet.
