This is the Danger Room. What you seen in there may shock and frighten you, but it cannot hurt you. The guards on the other hand will hurt you, so I would like to remind you too keep you hands, legs, heads, and all body parts inside the ride at all times or the guards will make sure you have none. Have a nice day.
*Caution: The guards don't aim well, but they have a lot of bullets, and nothing but time, and stragglers, to kill. Happy trails.
