Each challenge has 3 operators to locate. First, find yourself on the map using the in-game POV and map blueprint. Listen to the audio to determine where the target operator has moved to and place your ping on the map to make your guess. Guesses within 0.5 meters of the target earn 1000 points.
Operators CAN move between floors and there is a -500 pt penalty for guessing the wrong floor
Hatches may be open in some scenarios
Example: Below on the left is your in-game POV as well as the audio you would hear from Alibi. On the right is how the map looks after making your guess.
