The Hoover Dam scientists made several specimens that grew to full size. However, shortly before the Great War started, a Chinese infiltration and sabotage team discovered the secret laboratory and tried to destroy Hoover Dam so that the genetic work could never be used against them. Some of the Chinese stealth soldiers in Hei Gui stealth armor made it into Hoover Dam Sub-Level 1C, while others were planting bombs in the main generator rooms. One of the bombs went off prematurely and alerted all of Hoover Dam, including the guards in S1C. Things become cloudy in the reports due to the chaos that ensued, but suffice it to say that the Chinese were defeated, the generators were heavily damaged, and S1C was compromised. During the heated battle in S1C, several genetically altered creatures escaped into the halls. The guard in the guard post was ordered to leave and seal the exit hatch if ever such an emergency happened, and the guard followed orders well. A couple of Chinese stealth soldiers and four scientists were trapped in S1C after the hatch was sealed, doomed to either die at the hands or weapons of the enemy, be consumed by the escaped genetic creatures, or simply die of starvation.
