-respawns can be used to leave buildings faster, depending on how close you are to the door (town halls a pretty good example)

-When the game fades into Bucky's monologue right after the intro cutscene, you can pause the game and press respawn to skip the dialogue and the tutorial following. You wont be able to see it all to well so just make sure your game gets paused, you go down an option and select.
