I've built several particle disturbance sensors and given them to my squad at the start of a mission. The only details I can find about how to use them are along the lines of "Click on the Disturbance Sensor icon on the tactical display. Select 'Use Sensor' from the menu." I can't see this icon anywhere! What am I missing?

Use the sensor like you would a weapon - put it in your hand, then click on it, the same way you would pick between snap, auto, and aimed shots.

Medkits are used the same way.

    They are the equivalent of motion sensors from the first game if you wind up playing that one or know how to use those.

  • Thanks, that worked. Thanks for the advice about the first game, too! Jan 9, 2012 at 2:27

The other thing of note is how to use the display once you have it. It will show you all movement from anyone within an 8 square radius. It is best to use this before other people have moved. It will only show moving people, so if you have an alien hiding in a closet, it won't do much good.

Personally, I never could find much use for them, but perhaps others have.
