you can use it on any other difficulties if you want."

After calming down, head through the opening and refuel at the ammo cache in the alley. Check the open door on the right for weapons or items. As you exit onto the street, shoot any Infected, watching for Hunters in dark corners and Smokers attacking from above.

Enter the electrical station across the street. Ignore warning signs; you won't get shocked by machinery. Maneuver through the area, looking for Infected like Hunters or Smokers hiding behind cylindrical mechanisms.

The storage room on the right upon entering the electrical station may contain weapons or pain pills. Stay on the right side as the area opens up; the opposite end is sealed and holds nothing important. Enter the room on the right.

Pass the forklift and white tanks, then check the first-aid station for kits. Continue through the building and enter the lit room. Check the bathrooms behind you for goodies.

Use the hole in the wall to exit into the terminal. You may encounter a Tank here, especially if you didn't see one at the station's entrance. The tight corners are ideal for ambushes.

The terminal is large and can host an Infected army. The Horde may appear once or twice, or a Witch might be present. The rocky terrain can be difficult to maneuver due to rubble and objects.

Finding hand-tossed weapons or pain pills in the terminal is difficult as there are no rooms to enter; they may be on the ground or crates. Look for blue outlines.

Smokers are annoying here, appearing on the flat white roof. When you hear their voice, look up immediately. Hunters can hide behind downed suitcases and rocks. Boomers are easier to spot.

Avoid the red car parked in front of the parking garage; it's the only one in sight. Enter the garage.

Circle around the parking garage to reach the ramp to the second floor. Pass the ramp; you may find valuables at the dead end. Continue to the next floor.

The second floor has cars in unorthodox positions, Infected in dark areas, and possible pipe bombs and molotov cocktails. Be aware that the Horde or a Tank is likely to appear on this floor. A Tank can knock cars around, so be cautious.

Go up the steps and run across the walkway. The safe house is at the other end of the bridge. Take out any remaining Infected or Special Infected on the bridge and hurry into the safe house.

Leave the safe house and look at the bottom of the terminal. If a large group of Infected is present and you have a pipe bomb, use it. Otherwise, snipe them from the glass railing. If you hear the Horde, head to the right side of the balcony.

Shut the double doors and shoot a hole in one. The Horde will run to the door; pick them off through the hole.

Once clear, open the door and walk across the corpses. Check the big board rooms and other areas for pipe bombs or pain pills, following the corridor to the other side of the terminal.

Be aware of a possible Witch or Tank. The game tends to present one or the other at certain points.

After heading down the escalator, take out stragglers and head towards the van. After starting the van, the Horde will crash into the terminal. You can cover (press the cover button to crouch behind walls or objects) most angles of attack. Use a molotov cocktail or fuel cans upstairs to seal off the escalators, then pick off Infected falling from the balcony.

The van crashed through the steel grating on the far side of the terminal; head through. You may find ammo near the check-in area. Crawl through the luggage conveyor belt.

Stay on the black and blue conveyor belts unless searching for weapons or pills. Following the belt leads to a door into the main lobby. Use hand-tossed weapons to kill the many Infected here.

Search the lobby for a large Atlas statue; you will find hand-tossed weapons, upgraded weapons, and ammo at its base. Before going up the stairs on the far side, check the restaurant or Duty Free store.

Go up the escalator next to the store and look outside.
