Fourth Floor: Onestop Imports

Descend the stairs and proceed through the door to the east 4F hallway.

Carefully navigate the corridor, encountering four Slurpers. You can unlock the west door to the center corridor if desired.

In the southeast room, cross through a hole in a fence to find HANDGUN BULLETS and a FIRST-AID KIT on a bed. Warning: A Slurper may ambush you from below on Normal and Hard difficulties; run past it first to lure it out.

Return to the hall and continue through the end door to the west corridor.

Pass a Slurper and potentially two Double Heads to enter the northwest room.

Examine the coins on the desk to obtain a SILVER COIN.

Locate a note by a vending machine discussing riches and silver coins.

Insert the SILVER COIN into the vending machine to receive a can.

Examine the can to find the LIFE INSURANCE KEY.

Exit the room, avoid the Slurper in the hall, and pass through the blue light door to reach the center of 4F.

Take the elevator down to 1F to use the LIFE INSURANCE KEY.
