<h1>Build a wind trap and pressure pad, and link them.</h1>
Traps are vital to the overall security of the base. They allow you to protect important areas of the base without having to micromanage, although they are not infallible - skilled agents can sneak past without triggering them.
<br/>
All traps need a sensor to trigger them - move to the control room and look at the existing trap system, a pressure pad sensor linked to a wind trap and saw-blades trap. When someone steps on the pressure pad, the wind trap blows the victim into the saw-blades where they'll meet a sticky end.
<br/>
Add to this trap system by placing a new pressure pad sensor next to the current one, and a new wind trap in the alcove next to the existing one. Once built, click on the link mode button and connect the trap elements together. Left-click and hold while inside the sensor circle, and drag the arrow to the saw-blades. Then do the same from the sensor to the wind-trap. This will successfully set up your new trap system.
