Erebus is a community-made Attack/Defend Control Point map released during the Scream Fortress 2021 update. It is set in an haunted mine located somewhere in a forest. A nearby volcano and Hydro electric dam overflowing with lava have caused pits of lava to open up on the map.

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 will be 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.
