Sticking Gel

The Sticking Gel is an unnamed and fourth type of Mobility Gel cut from Portal 2.

Overview

 * Based on the blue paint appearing in the video game Tag: The Power of Paint, it was to allow players to walk on walls or ceilings covered with the gel. However playtesters tended to get nauseous after using it as its effect was very disorientating, hence its removal from the game.


 * Its sign to be used in Test Chambers was created and can still be found in the game files.
