Under the Enemy - Big Discoveries (Act 4, Chapter 1)

Under the Enemy - Big Discoveries, is the beginning of Act 4 in Evolutionary Conflict. When the squad finally enters the city outskirts, they find out that it is swarming with Demon Type II Guards. They also discover that the humans aren't aware that the demons are capturing Infectors and are trying to release the parasite inside them and resurrect them to help their armies because they are defenseless unless they do something. After they find that out, Corporal Jeff has a new message in his inbox. He is promoted to sergeant. More bad news is that Sergeant Grubbs was captured and is being held somewhere down in the prison yard area of the city. The squad fights their way there.
