Counter Strike Online Biochemical Apocalypse

In 2008, in order to strengthen the attack on hostile forces, the government secretly established the REX Biochemical Research Institute to manufacture biological and chemical weapons and improve the combat effectiveness of the army. The world's top scientist Anfred was fully responsible for it. In order to prevent future troubles, the hostile forces sent elite troops there. They carried out secret sabotage, but were intercepted by the military. The two parties fought a decisive battle at the REX Research Institute. Unexpectedly, the hostile forces exploded the experimental library, causing the virus to mutate. The mutated virus resurrected the dead soldiers, but deprived them of their consciousness, leaving only the consciousness of killing humans. All disputes turned into a common goal for each other. In order to survive, the two sides decided to temporarily put aside their grudges and join forces to fight against the biochemical virus. When they left the institute, they found that the entire world had been swept by the virus. In this biochemical virus leak, the person in charge of researching chemical weapons, Anfred, quietly disappeared during this incident. According to the investigation of the special forces, it was found that Anfred was inescapably related to the biochemical crisis leak.
