This power allows Cole to create an electromagnetic force field to protect himself from most forms of harm. Except for shotguns, the shield is almost completely impervious to gunfire, though it only blocks in the direction the camera is facing. While it's not strong enough to withstand explosives, Polarity Wall is quite effective against turrets and their mobile counterparts. The Polarity wall can also be used to block certain powers of Conduits, such as the Golem Conduits' "Gatling Gun" attack and Kessler's Lightning Bolt.
Cole can do anything while using the shield except attack (with the exception of Lightning Storm and Thunder Drop), which includes moving, jumping, gliding, climbing and grinding, making it useful to use in enemy-infested areas. The target reticle is used to control what direction the shield is facing, allowing Cole to move in any direction while blocking incoming attacks from any other direction. Polarity Wall can be upgraded to allow blocked damaged to be converted into energy, and to increase the size of the area covered.
