- Players must enter the Nightclub and memorize the four colors on the DJ booth from left to right.
- Players must then open the metal door and then advance until they reach the vending machine. This room can also be accessed by taking the ceiling vent in the main room.
- Players must shoot the colored buttons on the vending machine using a weapon with hitscan bullets in the order that was displayed on the DJ booth. If done correctly, the vending machine will turn green.
- After advancing to the top floor, one will be met with a secret compartment at the end of the room. This can be interacted with to obtain the Boss Keycard.
- The Boss Keycard is referred to as the "Special Keycard" when attempting to enter the Jetpack room without it being in the player's inventory.
