The Electric Eye reveals invisible units and has an unlimited lifetime. If enemy units get within a 200 radius of the Electric Eye, it will be revealed to them. You may have 2/3/4/5 Electric Eyes active at any one time.

Each Electric Eye has an ability that will allow you to destroy it, as well as an ability to detonate, silencing enemies in a 450 radius around it for 3/4/5/6 seconds.
