Ping

 is a covert quickhack in.

Overview
This quickhack reveals enemies and devices connected to the local network upon use.

It is very useful to quickly reveal all enemies within range of the hacked target. After pinging, a stealthy player might use this opportunity to pin every enemy before the effect fades, then plan out their take-downs. Non-stealthy players may use this information by sniping enemies through walls with Tech weapons, while being completely safe from enemy retaliation.

It has a default duration of 20 seconds at uncommon rarity, which can be increased to 38 seconds by the following:
 * 20% (4 sec) by spending attribute points in Intelligence.
 * 20% (4 sec) by leveling up Quickhacking.
 * 50% (10 sec) from the Quickhacking perk Signal Support.
