Rock Climber is a skill that can be given to a lemming in Lemmings 2: The Tribes. A Rock Climber can scale vertical walls, like a Climber, and is also able to climb overhanging terrain at an angle of up to 45 degrees. If it encounters a greater overhang than this, it will fall down. The Rock Climber is a permanent skill - once assigned to a lemming, it has that skill for the rest of the level.
