"This sensor will light up if an antlion is coming down this tunnel. More lights mean more antlions. When a tunnel lights up, we move a few turrets in front of it. Pretty simple, eh, doc?"

The Antlion Detector is a Resistance device detecting approaching objects.


Used in the Victory Mine by Griggs and Sheckley mostly to detect approaching Antlions, the contraption includes three traffic lights connected to a sensor. When it detects vibrations/movement, the lights and an alarm activate. The more vibration/movement, the more lights.

This device senses all movement, not just Antlion movement, as Gordon and a group of Vortigaunts set it off too.
