How to unlock Wall of Sparks
A Wall of Light is a type of defensive electric wall. These walls are in various missions. You can find/buy a gadget in the game called a Rewire Tool. When you find a Wall of Light, you should see a control panel nearby. Use the gadget on this panel and then get an enemy's attention on the other side to chase you so that he gets electrocuted. You may also possess an enemy and walk them into the wall of light, or throw their unconscious body into it (or carry it through to commit homisuicide).
