Order Billy to use the ladder in the room with new riddle

Use the stairs with leeches again (M6,9). Stop in the next room which you have previously bypassed while playing as Rebecca (M6,8). Separate the two playable characters. First, take control of Billy. Find the ladder in the room and use it to walk down. There are a few chests on the lower floor and correctly pushing them will be part of the riddle.

Important - Try to complete further steps according to the walkthrough, this will allow you to avoid trouble. If you will push the chest to a wrong place and you won't be able to move it anymore, leave the room with the riddle - once you return, all the chests will return to their default position.

Climb on the nearest wooden chests and position yourself in the place shown on the picture 1 - left from the silver chest. Move that chest as far to the right as possible - its final position is shown on picture 2.

Select rotate right from the option list

Retreat as Billy near the ladder (you don't have to go back to the very top) and switch to Rebecca. Walk as the woman to the control console on the upper level and interact with that object. Select Rot.R from the list. This will move the metal gate on the lower level to the right (by 90 degrees).

Again select Billy and use the fact that the gate is open to position yourself in the place shown on picture 1. Now you must push the silver chest to the wall at the top of the screen - its destination is shown on picture 2.

Go back as Billy near the ladder and take interest in the wooden chest closest to it - it is shown on the picture 1. You must push the chest to the opposite end of the lower area - utilize the fact that the gate is turned and it allows you to do it. The chest must be placed in the position shown on picture 2 (another chest will be next to it).

Once you complete all the actions, go back as Billy near the ladder, switch temporarily to Rebecca and select the Rot.R command again to move the gate to the right by 90 degrees.

Switch to Billy and position yourself near the middle wooden chest - the one you haven't moved yet. It is shown on picture 1. Start moving that chest towards the gate. Once the chest touches the gate, move it additionally as far to the right edge of the screen as possible - its position is shown on picture 2.

Move yourself away from the gate as Billy, switch to Rebecca and use the Rot.R action for the last time to turn the gate to the right. Now you can switch back to Billy and continue moving the wooden chest which is currently at the right wall. Move it to the opposite end of the room so that it will join the two chests that are already there - the destination point is shown on the picture above.

Now you can use the ladder and return as Billy to the upper floor. Select Rebecca and walk again to the control panel. Now select the Fill/Drain command. The bottom floor will be filled with water. If you have moved all the chests correctly then the ones on the left side of the screen will create a bridge shown on the picture above. Use it to walk as any character to the other side and reach the place where you can pick up the Handle.

Place where you use the handle

Once you obtain the handle (you can pick it up with any character) you will have some way to go back. First use the stairs leading to the recreation room (the one with pool table) (M6,6). Then select the door leading to the corridor in which previously Rebecca was attacked by a hunter (M6,5). This time you will find few zombies there whom you can easily kill. Once you clear the area take interested in the previously locked door . Walk towards it, open the inventory and select handle. Wait for the access to the new room (M6,11) to become unlocked and enter inside.
