When you get into the main core of gameplay in Resident Evil Requiem, it's when you're playing as Grace at Rhodes Hill Care Center. However, this center is on lockdown, and the only way out is through a front door with missing indents.

Upon further inspection, you'd see that the door requires something related to a sun, moon, and star. In true Resident Evil fashion, you have to gather items in order to solve a bigger puzzle to progress.

Meet the Cast of Resident Evil Requiem

Capcom recently revealed the voices behind Resident Evil Requiem's Grace Ashcroft and Leon Kennedy.

You'll soon learn that you need three quartz of those celestial bodies in order to open the door and escape from Rhodes Hill. However, those quartz are tightly locked away behind puzzle boxes, and it's up to you to unlock and open them.

Thankfully, there are a few ways you can get the Moon Quartz.

Where to Find the Moon Puzzle Box

Make Sure You Have Inventory Space

The Most Realistic Horror Protagonist Is A Terrified One

Grace Ashcroft being terrified of her surroundings doesn't make her weak, it makes her real.

The Moon Puzzle Box, which is what hides the Moon Quartz, can be found in the Chairman's Office. You're not alone in this office, so be prepared for that — and also be prepared that you don't have to sit in the dark the whole time. There's a light switch, but the Chairman actually doesn't care too much if the light is on, unlike other zombies.

Even better, there are a few different methods you can deploy to open this box, some of which don't require you to take even a single step away.

How to Open the Box

It's Time to Admit Resident Evil 6 is Great, Actually

The "worst Resident Evil game" isn't even that bad in the first place.

Pencil Method

The Pencil Method of opening the Moon Puzzle Box is clearly the main, obvious way that developers intended for players to figure out the puzzle. While in the Chairman's Office, go further into the office itself, and you'll notice a pencil sitting on the Chairman's desk.

If you remember when you first walked into the main area of the office, someone ripped a page out of the Torn Journal. However, we can see what was written on the page above, so long as we take the pencil and just rub it all over the paper.

Doing so will reveal the code for the puzzle box: Moon, Sun, Star, Moon.

This will also give you the Chairman's Note, which is one of the files that you need to collect.

Picture Method

In case you decide to just run past this room for the moment, there's another way to open the puzzle box, and it's in the Lead Researcher's Office. If you go to the desk, you'll see a bunch of pictures that you can interact with. The one of importance for us here is the one in the ornate frame.

Pick up the picture frame, zoom in and look at it, and then you'll realize that it just has the Moon Puzzle Box with the completed code in the background. With that, you can just run back downstairs and copy what you see in the picture.

Pamphlet Method

This is very likely an accidental method of figuring out the code, but it's literally how I solved it the first time I played the game, so it should count for something. If you remember from the Save Room early on, there's a Care Center Pamphlet that talks about the three main board members — alluding to each of them as a sun, moon, and star.

It actually puts them in the order of Moon, Sun, Star — which are the first three buttons of the code. And, considering that it's the Moon Puzzle Box, it is just a logical assumption to select Moon as the final button, as well.

With this, you're able to scratch your brain with a pretty fun way to solve a relatively simple puzzle, but you're also one step closer to escaping with your life.
