Let There Be Light
Having some degree of familiarity with the layout of the sugar mill, you should find your exit to be more adept and quicker than your entrance. You begin in the alleyway between refineries, so race along the ground toward the floodlight (picture 1) and then turn the corner, facing the ruins of Refinery 1.
6A
To your left is a cabin, which hopefully contains Adrenaline and other goodies you can use. Flee the scene, or stay and systematically drop those who seek to destroy you (picture 2).
6B
Let There Be Fright
Move to the middle of the refinery, which can be accomplished on either an upper catwalk, or a lower watery wade. (It’s at this point, or just after you pass Location 6B, that you should think about employing Adrenaline and racing all the way to the Safe Room.)
6C
Expect more Common Infected on the ground, usually with Special Infected lurking and ready to pounce, spit, or claw. Just to the right of the doorway (shown) is a ladder (not shown), which allows you to get up to a pipe and the continuation of a catwalk leading into the upper floor of the mill office (6E).
The Long and the Short of It
6D
If you had to abandon the upper route into the mill office (due to rescuing a teammate, or someone losing their way), the next best route is through the garage and out into an extremely soggy lawn area with the cylinders and container trucks. Rush around this location and into the office without delay.
Seeking the Soggy Safe Room
6E
Whether you arrive at the mill office via the upper floor or the side doorway from Location 6D, you are just steps away from the Safe Room, but you aren’t safe yet! Sheet lightning (picture 1) illuminates the sky briefly, but that won’t show the Special Infected that are likely to be waiting in this vicinity.
Beware of attacks from either side of the road, and even in the darkened rooms inside the building that houses the Safe Room!
