- Level Description

Overrun is a custom Nazi Zombies map.

Backstory
After the full scale attack on the United States by Soviet Russia, Alex Mason, Frank Woods, Joseph Bowman, and Jason Hudson fought their way to the Pentagon. When they arrived, they discovered the horrible truth: the Pentagon itself had succumbed to Element 115. Zombies now populated the building. The four agents equiped their M1911s, and began clearing out the Pentagon in search of President John F. Kennedy, Secretary of Defense Robert McNamara, and runner-up Richard Nixon. While fighting through the inner core of the Pentagon, Hudson discovered Doctor Adrienne Smith, a CIA designer, in a closet. At that same moment, Bowman is crowded into a small corner and mauled by zombies. The remaining four fought their way up the roof of building, and lauched flares. Luckily, a passing Huey saw them, and landed. The four are flown to a hold-out spot in Nevada. However, zombies had breached base.

When the Huey arrives, the pilots notice many figures running around and dead bodies. When the Huey lands, several zombies sprint towards it. Mason and Hudson shoot their M1911s and kill the zombies. Mason, Woods, Smith, and Hudson jump out of the helicopter and run to a tent. The Huey is then swarmed by dozens of the zombies, and the pilots are killed. The four agents the doctor reload their M1911s and prepare to once again fight the undead horde.
