Ping is a utility program which creates a noise distraction with a radius of 4 tiles. It costs 1 PWR to use, and has a cooldown of 4 turns. Ping can be bought from some Server Terminals for 450 credits.
To use Ping, select it in Incognita view, and then click on any tile. The noise distraction will be centered at that tile, and will be heard in the highlighted area.
The noise made by Ping is heard only by guards, not drones (which have no hearing), and not Sound Bugs. If Ping is used to distract a guard to a tile has has no valid path to, or a tile outside the boundary of the facility, then the guard will instead investigate their own tile.
If multiple guards are within range of the noise, they will usually all investigate it.
Ping is considered to be one of the best programs in the game.
