Step 1: When you log into the game, head to the back area of Biz Mart. Around the corner, you will find a strange box with a black liquid splattered around and on it. Once found, jump on the box. Note: This will teleport you to another external map. It is also single player.

Step 2: You will be teleported to a fuzzy version of Biz Mart. Head inside the store and talk to Sid. It looks like you'll be doing inventory for the night.

Step 3: Once you finish talking to Sid, head over to the 'EMPLOYEES ONLY' door. When you head inside, you'll immediately notice that it's dark. It's a long tunnel! Just keep walking forward until you reach the end of it.

Step 4: When you reach the second area, talk to Sid again. You'll then head into the 'EMPLOYEES ONLY' door again and see the same tunnel. Keep moving forward until you reach the third area. By this point, you'll start to notice things are becoming different. Talking to Sid, the dialog takes a bit longer to initiate. Once finished, go back in the long tunnel until you reach the fourth area.

Step 5: By this point, things are clearly getting serious. The notes on the walls have scribbles, the music and clock ticking are getting slower, and Sid's dialog prompt is taking longer. Talk to Sid again and then head back into the long tunnel until you reach the next area.

Step 6: Upon reaching the fifth area, you'll notice that the outside of the store is completely dark. Inside, there are various black splatter stains on the floor, a black substance dripping from the ceiling, and the light above Sid is red. Talk to Sid once more and read what he has to say. After this, head back into the long tunnel.

Step 7: When reaching the sixth area, the world is completely dark and void of life. When you exit the tunnel, there is a Flashlight item on the ground. Picking it up is optional, but continue ahead and reach the inside of the store.

Step 8: When you head inside the store, Sid's office is locked. Unlike the previous areas, you can actually enter the office now, but you will have to find a key to access this part.

Step 9: Head back outside and go around the store. When you spot the vending machine, you'll notice there is a key inside of it. Click/tap the selection pad on the vending machine to obtain the Grey Key item.

Step 10: Head back inside and equip the Grey Key item. Once equipped with the key in your hand, use it on the door. The prompt should now update for you to go inside the room now.

Step 11: Once you head inside, you will briefly catch a glimpse of the inside of the office. However, you will be blocked from entering any further and be kicked from the experience. A message will display telling you that you have been disconnected along with the message accompanying it. You should now obtain the 'endless shift' badge. Congratulations! You made it to the end of the mini-quest!
