This version of spy suit has the ability to send out an EMP wave in medium radius. All devices hit by the wave are destroyed and enemy players can't use their special ability for a short period of time. This downtime is accompanied by distorted vision. The EMP can remove tags and has a chance to stun drone or disruptor Mercs who are using their ability when the emp hits, ending the ability and resetting the cool down timer, due to the electronics. The disruptor merc has to be far enough away otherwise the disruptor blocks the activation of the overcharge.
Tip: the wave expands slowly enough that an experienced opponent can be able to determine your location. So unless you're hiding as the hacker I recommend moving after using.
