Approach the pipe and press the jump button. Sam grabs hold of the pipe. Ascend the pipe to its peak and leap onto the ledge. Spot the burning warehouse in the distance. You're headed that way. There's a wire just to the left of your current position--it's a perfect zip line that can take you straight to the burning building. Lambert offers some encouragement (you'll have help in navigating the burning building). Stand below the wire and leap straight up; Sam grabs hold of it and slides into an open warehouse window.

Sam must find a way to reach the burning building in the distance.

Open the door and move slowly toward the room across the hall. If you peer left, you'll notice the hallway blocked by a tremendous blaze. As stated, move slowly into the room because as soon as you step inside, the floor gives way. Grimsdottir apologizes for your predicament and suggests a detour to a nearby stairwell.

Exit the room quickly (stand up and run if you're currently crouching) and head toward the blaze at the end of the hall. You'll spot an open doorway on the left. Run inside. Move to the far end of the room and notice another open doorway, this time on the right. You've bypassed the blaze by taking the route through this open room. Run to the stairwell at the end of the hall. Note the ceiling caving in behind you--but you're safe in the stairwell, as long as you don't step into the fire.

Start down the stairwell. Hug the left railing so you avoid the patch of fire raging on the stairwell's right side. Proceed down one flight of stairs and spot the open hallway to the right. The floor has given way to the blaze, but there's a well-placed pipe just overhead. Stand under the pipe and leap straight up; Sam grabs hold. Maneuver down the hall by going hand-over-hand along the pipe. You can pull Sam's legs up if you wish.
