E1MS: The Dim Slough

**The Dim Slough** is the secret mission of The Foothills, taking place at a small factory and a sewage system. To access it, the player must find a secret entrance in E1M2: Down On the Farm. Upon entering, the Swamped Achievement is received.

### Main Areas

#### Beginning

The level starts in a cave, with a Rat. After that, there is a ladder leading up to the surface. At the surface, there is a trapdoor requiring a Blue Key, as well as a Shotgun. From there, there are two Leathernecks, and a small shed surrounded by puddles of water. Inside the shed there is a Pistol. There will be two Mages from the left, coming from the outside of a small factory. Behind the shed, there is a Possessed Scarecrow.

#### Outside the Factory

When the player walks in, they will alert a Black Phillip, which will come from the right to attack the player. When walking some more to the right, they will alert a Mage, which will follow them similarly to the Black Phillip. To the right of the factory, there are two Black Phillips. Behind it, the player will encounter a Black Phillip and then a Possessed Scarecrow. At the end of this path, there is a red key.

#### Outside a Pipe

The player must now backtrack to the start of the level, and then go to the area to the left with a pipe near it. In that area, there are many Mages. Inside a broken down building, there is a Shotgun and a Priceless Diamond.

#### Sewage System

After entering the pipe, the player will climb a ladder to a small room with two Rats in it. After that, there is a large pipe leading down into a sewer. Inside there are many Rats, and a Pistol. There is a switch which gets rid of the gates. Once those are down, there is a ladder leading into the factory.

#### Inside the Factory

Now that the player has entered the factory, there will be two Mages on the second floor. After that, there are a few mages on the next floor. Once that is dealt with, there is a door which requires a Red Key at the bottom floor. If you already went through the outside of the factory, you should already have it. When opened, a passageway with a Leatherneck will be revealed. At the end of this passageway, there is a door leading to a large room with Leathernecks, Mages, and a Possessed Scarecrow on the upper floor. On the upper floor there is a Blue Key as well as a switch which removes the gate separating the outside of the factory from its interior. The player must now backtrack to the start of the level and go to the trapdoor which requires a blue key.

#### Exit

The trapdoor leads to a chamber containing a Leatherneck and a Mage. From this chamber, there is a ladder leading to a gate, guarded by a Possessed Scarecrow. The player must then interact with the gate to end the level, taking them to E1M3: Old Time Religion.
