Mill Escape

In the Mill Escape the weather has begun to deteriorate as the Survivors turn around to bring the fuel back to Virgil's boat. Due to storm clouds blocking out the sun, all the Wandering Witches from the previous level become normal again and they sit down instead of walk around. This chapter has more Construction Workers than the previous chapter, but fewer Witches. You should try avoid the water as it will cause you to move more slowly.

There is also an unavoidable panic event during the whole level. As the Survivors move through the Sugar Mill, the storm will become stronger for a short amount of time. During this time, the Survivor's vision is shorten and a Horde may attack. It is wise to stay put until it clears up enough.

When the hurricane hits with full force, mic chat can be severely affected due to the way the audio channels layer. This is likely an intended effect by Valve in order to maintain an aura of realism. While you can still use the mic, do not expect fellow Survivors to hear you clearly or at all sometimes. This effect is lessened indoors.

Trivia

 * Oddly, while calling the elevator up triggers a horde, riding the elevator up or down does not. However, it could be argued that the severe storm may be blocking out the noise of the elevator to the horde.
 * When going through the flooded sugar mill, there are fewer Witches than in the previous chapter.
 * According to the writing outside the gas station safe room, a lot of the town evacuated with their kids and dogs. This explains why there are no children or dog infected despite there being a playground in the campaign.
