Hollowbody Guide: How to Unlock the Room 13 Safe
Find the clues, connect the timeline, and grab the Long Key with our complete walkthrough for Hellen's room.
Quick Answer: If you just want to grab your loot and move on, punch 2052 into the Room 13 keypad. This immediately unlocks the safe so you can claim the Long Key and continue your playthrough.
Investigating Hellen’s Quarters
Shortly after surviving your first true combat encounter in Hollowbody, you will find yourself in Room 13. A locked safe sits on the wall, and ignoring it is not an option. Inside rests the Long Key, a mandatory story item required to open the spare gate and progress to the next area.
Hollowbody refuses to hold your hand. You will not find the code scribbled on a piece of scrap paper. Instead, the game forces you to engage with its environmental storytelling. To crack the lock, you must investigate the room’s deceased former resident, Hellen Bridges.
Crucial Clues to Collect
Before staring blankly at the keypad, take a walk around the dimly lit room. You need to track down specific pieces of Hellen’s past to piece the password together.
- The graduation photograph
- The birthday photograph
Doing the Math
Figuring out the code requires a little basic deduction based on Hellen’s life milestones. Other documents in the room establish her birth date as October 2025. The two photos act as the missing variables in this equation.
Examine the graduation picture closely. You will see three women standing together, and Hellen is noticeably pregnant. Next, check out the birthday photograph. Here, Hellen is celebrating alongside a child who appears to be roughly three or four years old.
By calculating the child’s estimated age against Hellen’s pregnancy, you can pinpoint the exact year she graduated.
Timeline Breakdown
| Clue Source | What It Shows | What It Means |
| Room Documents | Born in October 2025 | Establishes her baseline timeline |
| Birthday Picture | A child around 3 to 4 years old | Takes place several years after graduation |
| Graduation Picture | Hellen is heavily pregnant | Ceremony happened roughly 4 years prior |
Running these specific milestones against her established birth year leads to one logical conclusion. The graduation ceremony took place in the year 2052.
Claiming the Long Key
Walk over to the wall safe and interact with the keypad. Enter 2052.
The door will swing open, allowing you to snatch the Long Key. With the key tagged for the spare gate now in your inventory, you are ready to push forward. Hollowbody constantly rewards players who take the time to soak in their surroundings. Get comfortable analyzing photos, reading documents, and connecting the dots, because this is just your first taste of the game’s excellent puzzle design.
