Function: Elevated walkways above maintenance tunnels, warehouses, engineering bays, or alongside broad corridors.

Access: Ladders or ramps; without these, PCs need Climb, High Jump, or Leap → Grab an Edge → Climb to reach them.

• Movement:

  • Wide catwalks: normal movement.

  • Narrow catwalks: difficult terrain; unstable or railing‑less sections require Balance (Acrobatics).

• Risk: Falling or being shoved off inflicts standard falling damage.

• Cover: Creatures on a catwalk can usually Take Cover; depending on rail height and material, cover might be automatic.
