In places such as The Office, The Barge, and 125 Street Station, you can perform a Blazing environmental move. In order to perform this move your enemy must be in the danger zone, then perform a Blazing taunt at one of those places. For The Office, when you perform a Blazing environmental move, a cinematic view of you throwing your enemy out of the window will happen. For The Barge, it will do the same thing except your enemy will be thrown into the Hudson River. For 125 Street Station, your enemy will be thrown into the path of the train and get run over.
