Under the Enemy - Confrontation (Act 4, Chapter 7)

Part 1
In Under the Enemy - Confrontation, Alpha 9 squad finally makes it to the bottom floor. This floor is the longest floor and the squad is mostly seperated at times. After they get through half of the area, they cannot go back and are in a warzone between Type IV Demons and the Demon Leader. After trecherous fighting, they make it to the throne room.

Part 2
In the throne room, the leader states, "You should have been crushed with the Infectors". During the battle, the squad has to face two unknown advanced hierarch guardians. Then, they face the leader. After 10-15 minutes, the leader smakes his hammer and temporary knocks out the squad while he escapes on his pet Grabus.
