Grace’s journey through the Rhodes Hill Chronic Care Center in Resident Evil Requiem is full of obstacles. And zombies with weapons is just one of them.
In order to properly navigate through Rhodes Hill to escape it, you need to find some key items to open up a door to get outside. Naturally, because this is Resident Evil, and nothing is ever simple or without some kind of silly puzzle standing in your way.
Another Sun, Star, and Moon puzzle stops Grace in Rhodes Hill, but there’s also some annoyances that stop you from finishing it. Here’s what you need to do to open up the Lead Researcher’s Office puzzle in RE Requiem.
Lead Researcher’s Office puzzle solution in Resident Evil Requiem

The solution to this puzzle can be found within files found earlier in the game in the Chairman’s Office, including Lead Researcher’s Picture 1 and Lead Researcher’s Picture 2. In these photos, you can see the solution to open up the device in the background.
First, you need a special item to open up the case, which is the Corrosive found within the Conference Room in Rhodes Hill. Getting to the Conference Room requires encountering the massively obese Chunk enemy and getting it to leave the area so you can make your way to it.
There are a number of zombies in the Conference Room, including a singer who has no issues hitting the high notes. But once you have the Corrosive, you can bring it back to the Lead Researcher’s office to melt the lock and gain access to the puzzle.

The puzzle solution to open up the device in the Lead Researcher’s Office in RE Requiem is as follows:
- Star
- Sun
- Moon
- Sun
Inside, another key item for Rhodes Hill can be found. Grace’s journey continues onward, however, so keep safe and be ready to fight if necessary.
