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 Contruction Workers than the previous chapter, but less witches. You also should try avoid the water, because when you go in there, you will move slow.

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 Sugar Mill there are fewer Witches than in The Sugar Mill.
 * The Mill Escape is by far the easiest campaign for Survivors to get separated from one another.
 * According to the writing outside the Gas Station saferoom, a lot of the town evacuated with their kids and dogs. This explains why there is no child or dog infected despite there being a play park in the campaign.
