Ambush has been haunted and creepified. Welcome to your doom!
Erebus publicity blurb

Erebus is a community-created Attack/Defend Control Point map released during the Scream Fortress 2021 update. It is set in a haunted mine at night, located somewhere in a forest. A nearby volcano and hydroelectric dam overflowing with lava have caused pits of lava to open up on the map. It is a Halloween version of Ambush.

In Erebus, the goal of the attackers, BLU, is to win through a series of stages in order to win the map. Within each stage, the attackers must capture two control points, A and B, which are held by the defenders, RED. Point A must be captured before the attackers can assault B.

Erebus was contributed to the Steam Workshop.


The following locations are told from BLU's point of view

Stage 1, Point A

Stage 1
  • Tree Stumps: A name given to an area right outside BLU's right spawn exit, containing multiple tree stumps.
  • Lower area: This is a relatively small area found right outside BLU's left spawn exit. When compared to the Lumber Yard, the Lower Area is ever so slightly lower.
  • Lumber yard: The location of the first point. It's filled with saws, logs and wooden planks.

Stage 1, Point B

  • Sawmill: The large wooden building used for separating point A from point B. It has many corridors and acts as a direct line of approach to the final point.
  • Mineshafts: There are two mineshafts running underground. Both of them act as a flank route leading up to point B, and both of their entrances are at the Sawmill's sides.

Stage 2, Point A

Stage 2
  • Ravine: This is the long, depressed ditch which takes up a shape of the letter "L".
  • Cliff: On the Ravine's left side is the Cliff, accessible by crossing a wooden bridge up to it.
  • Cave: Another way to access the Cliff is from a cave on BLU's left side.

Stage 2, Point B

  • Sniper's deck: Right in front of the Point A would be the Sniper's deck, a tall building overviewing the next point.
  • Shed: And just left of the Point A is a tiny shed imbedded into the surrounding terrain.
  • Left Flank: Above the aforementioned Shed is flank route wrapping around the left side.
  • Central area: In between the Church and the Sniper's deck is the Central area, a relatively open location filled with many platforms, bridges and other map geometry.
  • Church: The Point B itself is in encased within a stone Church located on top of a hill-like structure.

Stage 3, Point A

Stage 3
  • Building 237: A building named after the sign displayed on it. It is located up on the left side, from which it slowly ascends up to the Point A on the right.
  • Yard: Directly opposite of the Building 237, also on the right side, is the Yard.
  • Elevation: This is the resting place of Point A. It is an elevated wooden platform connecting the Building 237 with the Computer room.

Stage 3, Point B

  • Computer room: The room which serves as a direct path to the final point. As the name implies, it contains many servers and computers.
  • Under Flank: Left of the Compute room is route which dips under the ground for a few moments before coming up on the Propane Tank's left side.
  • Propane Yard: As the name implies, the Propane Yard is a large yard with a red propane tank in it, as well as the final capture point.
  • Red Shed: In front of the Propane Yard is a medium sized house overlooking it.
