With our help you will see that knowing How to Complete Chained Box in Silent Hill 2 remake is easier than you think.
The Chained Box is a major puzzle in Silent Hill 2: Restless Dreams, set within Otherworld Brookhaven Hospital, required for discharge. James is thrown right into a nightmare upon completion of Brookhaven Hospital, only to be tricked by Laura. Now there are Bubble Head Nurses wielding knives, Lying Figures that explode on hit, and ninja-like Mannequins lurking in corners.
You need to solve the Chained Box puzzle for a clean exit in Silent Hill 2 remake from the Otherworld. The following is the breakdown for the Chained Box.
The Chained Box puzzle has a total of three pieces in it: two puzzle pieces, and a key. In order to obtain the -1 Elevator Button and reunite with Maria to finish Brookhaven Hospital, you'll have to travel through every floor and solve the problem associated with said floor. First, find the Lapis Eye Key and bring it to the Chained Box. This will unlock the first chain. For now, that's it.
You can still follow the map, even though James and I have never actually visited this site. Once James has arrived in the room of the Otherworld - situated above the Dayroom - he should proceed to take the elevator up to the second story. The elevator doesn't go all the way to the third story, so you'll have to use the western stairwell to reach this particular Otherworld level. It leads directly to Room 4 for the Exam. The first order of business is to use the Instrument of Force on the dummy. It demolishes its arm, and in the process a hole in its skull is revealed, which implies something should be inserted into it - maybe a faux lobotomy of some sort.
Still on the third floor, go to the ladder that leads down to the first floor, to the west of where the dummy stands. With so many foes packed into tight areas, this part of the world is really tricky to get across. As the Nurses, Mannequins, and Lying Figures spawn in this Brookhaven Hospital version, you should use the Handgun to thin out the adversaries. Find a hole in the big chamber above Storage and Restroom and insert the Key of Bliss to execute your lobotomy. To reach this location, go to Medical Records.
Go back to Exam Room 4 and, with the Key of Bliss in your possession, acquire the key for the Lapis Eye.
The second half of this puzzle is located on the west side of 2F. The rest of this puzzle can be completed without having to travel to another floor. To access chamber M2, head left from the Chained Box and pull out the chain. On the floor in here is a note on the wall with a calendar page that holds the solution to this cell. The four-digit code for the Chained Box is reflected on each line of this note.
First line gives you the first digit of the code of the four-digit code; the other lines refer to poisons in the sink. Look at the number of medicines in M2's sink and write the second digit of the code.
The third sentence is about when the horn happens. That leads nicely into the last line, which is about how many times the light outside your room goes off. In M2 there are two holes: through one hole, a light flickering in some predetermined manner is shining toward the ceiling. Count the number of flickers to get the next digit.
You'll find this number on the horn, too. This is confirmable by fiddling with the dial in M1. Look for how many times the light blinks and set the hand and such. On Normal puzzle difficulty, there will be two of these.
1 6 2 2 is the code to the Chained Box Calendar Page, as this will confirm.
Head east on 2F; it will take you to L2 and you will only have to break one more chain. Position the wheelie unit through the door out of this room, facing towards the wall of L3. You can jump up into the restricted area in the Observation Room to get in and take care of any Nurses trying to assassinate you. First head south to grab the key to the director's office; it's out in front of the TV in the observation room. Go up the ladder to reach the Treatment Stretcher.
Activating the Generator above the Restroom on 3F will turn on the Treatment Stretcher, so you have one less piece of the puzzle to deal with. Hitting the power button will burn the code into the Stretcher. Simply head back to the Chained Box and input the second code, 9 6 5 9, to see what's inside.
