|Map type||Attack / Defense|
Steel is an official Attack / Defense map.
The map has five control points, and is unique in that the final point is available for BLU to capture at any time, while the first four points must be captured in order. As points A through D are captured in order, various routes open for BLU and close for RED.
- Capturing point A opens nearby doors leading to Points B and E.
- Capturing point B opens nearby doors leading to Point C and switches RED's spawn.
- Capturing point C creates bridges to reach Point E.
- Capturing point D cuts off RED's direct access to Point E, and summons railings for the bridges leading to Point E.
