This season 7 week 8 legendary quest requires you to converse with characters to identify an Infiltrator.

This quest requires some travelling in order to go to 5 different NPCs to talk to them. I would recommend landing at a UFO in order to cut down your travel time in order to get this quest in a single match.

There are UFOs parked at Camp Cod, The Durrr Burger and Dirty Docks among a few other places. You could always shoot one down and high jack it from a trespasser.

When you have the UFO travel to 5 different NPCs and talk to them. To help you plan the fastest route there is a map below with all the locations of NPCs. I'd recommend staying away from Riot and Guggimon as they are hostile.

When you find the imposer they will become hostile so be ready to take them down or run.
