Level 598, or the Hotel Hallway, is a hotel hall way that continuously extends, when you believe you come to the end of the hall way, you don't. It has manila walls with a square pattern carpet, and each room has a number that starts with what level you entered on, it starts when you exit Level 597, you exit from the window on the floor, but the moment you look away from the window it disappears and the continuation of the hallway appears. The numbers on the doors exponentially increase, there is no limit, if you started at 300 and walked continuously you could find yourself at 3002343.
There are very few hotel doors that actually open, but that depends on how you open the doors. Sometimes the doors are unlocked and you are allowed to enter and sometimes while moving to the next level in the elevator you might find a keycard in your pocket or hand with a randomly generated number on it, but it will always start with the level number you are going to. This is very rare, but it is your best bet at moving to the next level. But be warned if you enter an unlocked door, unannounced and not allowed you will find the "Visitors" No one has ever returned from the visitors, so unlocked rooms are extremely dangerous.
If you obtain a keycard for a room you can drag your keycard against the scanner and enter the room, when you enter the room you will find restroom immediately to your left and a short hallway in front, when you continue you will find two beds, a tv, two desks, a tv stand, 1 chair, two ottomans, two nightstands, a fridge, and a microwave. All the appliances work
