Left 4 Dead/The Crane

You're in the employee room of a hotel, and are leaving by the back exit.

Route

• Exit hotel, turn left.
• Climb the fence by the overfilled garbage container.
• Climb the back of the truck and the fire escape above, entering the first available window set.
• Go up the stairs in the back of the building.
• Exit the building and head to the crane.
  • Pull the lever to lower the crane - this alerts the horde since the crane is squeaking.
• Walk across the roofs - turn right, right, and left.
• Straight into Merril Law Office, and exit the window to the next building.
• Turn left, go to the exit down the stairwell, and cross the cubicle to the exit sign - follow the exits until you reach the ground floor.
• Take the exit to the main street.
  • Watch the car alarm - one armed car is to the left of the main entrance.
• Once outside, enter the storage shop to the left, and beeline to the saferoom.
