The Climber is an unused powerup that is supposed to function like the Floater but is a timed powerup instead of a holdable. It can only be obtained through console commands or in some of the old PadMaps. Altough broken, it's supposed to allow the player to fly when pressing space instead of jumping. (But instead it just disables the ability to jump entirely) The Climber can still be acessed through console commands even in the latest version of WoP, however the icon and model have missing textures, and the Climber powerup does nothing (yes, it doesn't even disable jumping)
