The zipline is a piece of equipment cut from Counter-Strike: Condition Zero Deleted Scenes.
The only hint of its possible appearance is the presence of a viewmodel and worldmodel. Much like its real-life counter-part, it would enable a user propelled by gravity to traverse from the top to the bottom of the inclined cable.
