EQUIP a trapwire. FIRE to place a desctuctible and covert tripwire at the targeted location, creating a line that spans between the placed location and the wall opposite. Enemy players who cross a tripwire will be tethered, and dazed after a short period if they do not destroy the device in time. This ability can be picked up to be REDEPLOYED.
A well placed [C] Trapwire between high-traffic areas is perfect for informing your team of enemy rotations.
While [X] Neural Theft grants vision of enemy players, it only snapshots their location at the time, not updating if they move.
[E] Spycam becomes far more valuable on defense as it allows you to exist as a second pair of eyes on a bombsite if your teammate(s) holding that site dies.
