In the starting room, if the player goes behind the throne, there will be a large button. Upon pressing it, a door behind them will open, revealing a bunch of toilets and a bath, along with the boaster and some ammo.
The revival, although isolated, is quite easy to obtain. Simply push the button in front of the gate and it will open. If the gate closes while a player is still inside, they won't die but anyone can open the gate from the outside. The player also has the option to open the gate from the inside as well.
