Summary
The level begins with the Player arriving at the Administration Complex. As he steps out of the elevator, a cutscene takes over and shows Counselor Swann arguing with Dr. Betruger over a video com. Swann states that the situation is out of control and the UAC is assuming control here. Betruger is completely unfazed by the chaos surrounding him, and tells Swann that he'll handle this matter on his own. He then cuts off the transmission. Jack Campbell opens up his weapons case containing the BFG and prepares to execute "Plan B."

The Player fights his way from the Lobby to the Alpha Labs entrance. However, the doors are locked and he must find Director William Banks' PDA. He also encounters a dying marine E. Webb who tells the Player he was ambushed and that there may still be other marine teams out there, then dies.

Several new elements are introduced in this level. The Player acquires two new weapons: Grenades and the chaingun. After opening the Executive Office doors from the Data Library, the Player is confronted by a new enemy: The Pinky Demon. In addition, Sergeant Kelly contacts the Player over the radio and informs him that there is some kind of unidentified growth taking over parts of the base. This growth is later seen in Malcolm Betruger's office. The demons also demonstrate their ability to teleport here.

After acquiring Banks' PDA from Betruger's office, the Player fights his way back to the Alpha Labs doors and gains access to Alpha Labs Sector 1.
