Mann.Co has found a new deposit of liquid australium beneath an old oil rig that was set to be demolished. After the news of this deposit RED (Reliable Extraction Division) and BLU (Butane Liquidation Unit) rushed to what is left of the oil rig. Now, both teams must fight while the oil rig burns the remaining petroleum in order to claim this deposit of australium for themselves.
Demolition publicity blurb

Demolition is a community-created King of the Hill map released during the Summer 2025 Update. Taking place on an oil rig, it features an industrial theme and has multiple flank routes.

Demolition was contributed to the Steam Workshop.

Locations

  • Spawn: The two spawns are located directly opposite each other, with only a gap composed of deadly water separating the two. Each spawn has two exits, with the main exit facing away from the control point.
  • Antenna Tower: Directly infront of the spawns is a large radio mast with a small room at its base. It leads to the Helicopter Pad building.
  • Shortcut: Separating the spawns from the control point is a wall with a one-way gate, accessible by taking a right/left turn after exiting the spawn. The gate can only be opened by the team whose side it belongs to, and even then it cannot be opened from the direction of the control point. Furthermore, the team which captures the control point has their Shortcut temporarily closed. Above the wall is an invisible barrier preventing players from simply jumping over it.
  • Helicopter Pad: Adjacent to the Shortcut is a square building with an occupied helicopter landing pad on its roof. Going through it takes one to the Furnace room.
  • Furnace: A small building containing a coal-fired furnace and two large funnels. Its exit leads to the other side of the Shortcut and to the main control point.
  • Offices: On the left/right side of the control point is a medium-sized brick building with two floors and a basement.
    • Back Catwalk: Attached to the back side of the Offices is a metal catwalk hanging right above the deadly waters below. Going below the catwalk is a ruptured gas pipe spewing out deadly fire. A one-way gate separates the Back Catwalk from the interior of the Offices.
    • Basement: The lowest level of the Offices can be accessed by an outside staircase originating from behind the Furnace; it contains a medium health pack.
  • Crane: To the right of the control point is a concrete platform holding a massive crane, beneath which is a small health pack as well as a pad that launches players towards the control point when touched.
  • Control Point: The central control point is suspended on a platform, in between the Crane and the Offices. It is connected to each team's side by a wooden gangway. Capturing the control point sounds a loud, team-coloured whistle on top of the Crane. As long as a team is in possession of the control point their Shortcut is sealed off, requiring them to go through the Helicopter Pad and then through the Furnace to reach the battlefield.
