Whenever you get picked to be the Impostor, you will have the ability to use vents to travel around the map much faster than an ordinary crewmate. To vent, walk over to a highlighted vent and press , use  and  to select where you want to go, then press  to exit the vent. For this trophy however, you must win a whole match without using a single vent. For some players, this is not too difficult of a trophy too worry about. For others, who may be experts on using vents, will find this trophy rather different from their usual playstyle. If you are playing in a 2 Impostor or 3 Impostor game, this trophy shouldn't be too hard since you will have teammates to help carry the win since they can use vents and not prevent you from obtaining this trophy yourself. With this in mind, you can pretend to be an ordinary crewmate by faking your tasks, while also picking off other players when you can. Once you and your Impostor teammates win the match and if you never used a single vent once, the trophy will pop.
