Get to the RPD (Leon)

After the initial cutscenes, run towards the door and push it open to trigger the next cutscene (a non-interactive cinematic the game plays automatically). You will automatically pick up a torch.

Turn left, run to the end of the aisle and go through the door past the injured police officer.

Make your way to the end of the next passage and go through the slightly ajar door for another cutscene after which you'll be thrown into your first battle.

Deliver two headshots (shots to the head) to stagger your foe, shove your way past him and go down the aisle where he's standing to find a key hanging on a board.

Take the key and go back down the aisle, shooting the zombie again if necessary.

Take a left down the other aisle where you'll come to a locked door. Use the key you just picked up to open it.

There are three zombies in the room but you don't need to fight them. Your goal is the door to your left as you enter the room.

Warning: One of the zombies will knock over a trolley blocking your route. Run down the aisle immediately to your right, turn left at the end and run down the next aisle past a zombie as he knocks over another trolley.

As you approach the door, you will trigger another cutscene where you meet Claire and make your escape.

When the opening credits and next cutscene (a non-interactive sequence) are done, you will find yourself surrounded by the undead. Run to the right of the female zombie facing away from you.

Make your way around the burning cars and a little further ahead, you will see an alley to your left.

Run down it and follow it to the end. You will emerge in sight of the police station.

Pick your way through the path formed by the stationary cars.

Open the gates for another short cutscene and go through the doors in front of you, unlocking the Welcome to the City of the Dead trophy.
