You're gonna want to bring the prop disguise kit and the drone on this mission Agent.

locate an exit of a map, preferably on near the middle of the map that you can move to a different exit depending on the course of the game. Next pull out the prop disguise kit and find an object that would match the area. After that pick a spot with the new found item you will be hiding at the exit as and wait.

Now that you have your nest picked pull out the drone and activate it, then disguise to the object you had saved. Once your done is active and you are a prop swap to the drone. At this point you should be your prop of choice and also be active as your drone. Now fly around the map looking for players
the drone has infinite range and NO TIMER attached for how long you can fly around as it.

once you've found a gamer use the drone's specialty marking targets. After you've found and marked your target you have two options from here Fly around them like a bug they can't swat and continue to mark them till they die or progress the game or find a new player.

Option one, YOU want to keep following the player right? well you now will be engaging in gnat gameplay. all you need to do keep marking the player and become progressively more annoying as the time goes by. Fly in their face at their feet around them, pretty much make sure you know they're there and they know you're there flying around them every living moment. Some player will start to break their cover just to get rid of you, but who's gonna win in this fight? you the little bug that flies extremely fast or a gamer who needs to hit you out of the sky? YOU DO once you confirm they would rather shoot you and drive their attention to you, you have officially won. by the player shooting at you pretty much says
"i would rather get rid of this drone than stay in cover and attract guards constantly to my location."

Option two, you want find a different player? That's fine, fly around until you've found your favorite gaming goober. once you've decided on a target go to option one.

now that you've found your player and the game as progressed to the end bit where the case is on the move, you who has been sitting at the exit must judge what exit you think they would go to, most likely the closest one. If not already at that exit run to it and get there before the player with the case.
Hide in prop mode and wait for your free delivery to bring you that W. When the player who has the case feels like they're about to win hop out of prop mode and mow them down, You have just now taken the case and victory away from the gamer. double points if the player who had the case was the one you followed as a drone.

congrats on making someone hate you. I hope to see more of us out there agent.
