Radar jammer

The Radar Jammer is an equipment item that scrambles nearby players' motion sensors and HUDs when deployed and also makes their screen flicker and flash as if they're taking damage. While it can create chaos for enemies, it has the same effect on teammates.

The Radar Jammer is similar in appearance to the Power Drainer, except for its reddish-brown metal color and a red glow instead of blue.
