| Players enter a metallic room themed to look like a rusty bomb shelter from the 1950s. This room would be the final room in the theme, and is designed to be very difficult. |
Inside the room, the actual entrance to the shelter is locked by four puzzles located on the two walls. |
Each puzzle needs to be solved in order to unlock the door. Puzzles require repeated actions by players, as dictated by the puzzle instructions. Puzzles also require information from other puzzles to solve - this is to be coordinated by the user reading the instructions. |
| Instructions on how to solve the puzzles are located in a jukebox located in the back of the room. In order to activate the jukebox to flip through the pages, a numerical password from another room must be entered. Without this password, the room is impossible to solve. With each page flip, the jukebox plays increasingly loud and intense music to distract the users and make it harder to communicate. |
There are occasional power surges, which require a player to climb a ladder, open a fuse box, and flip all the switches. Until the switches are flipped, the puzzles turn off and no progress can be made. |
A display on top of the shelter door displays how much time is left until the bomb is dropped, indicating the time to solve the puzzle. The time left is dependent on how many players are in the room, as more players make it easier. |
