How to Reach the 10th Floor at CEG Headquarters in Silent Hill: Townfall

Players navigating the tense “Inside CEG HQ” mission in Silent Hill: Townfall now have a clear path to the game’s 10th floor, but only after solving a layered puzzle that hinges on a security door code and a carefully chosen lockbox. In the mission, protagonist Simon is tasked with reaching the upper levels of the CEG Headquarters, yet the elevator demands a level 10 access card he does not possess. Since he is not an employee of the company, Simon must print a new card using the security office computer — a task that requires first uncovering the code to the locked door and, crucially, opening only the correct box. The full solution, including where to find the code and which box belongs to Richard, is detailed below.

Cracking the CEG Security Door Code

Once Simon enters the CEG Headquarters, the elevator immediately refuses to move without a valid access card. The way forward begins in the maintenance room, where a subtle hint is left for the observant player. A strange whiteboard drawing, paired with a cluster of lockboxes, points toward the answer. The board displays dots, lines, and the number 4, and the pattern is straightforward: begin with “4” and then press the remaining numbers in the same sequence shown on the board. Following that logic, the CEG Headquarters security door code is 4895.

With the code in hand, players can finally print a fresh access card and lift the elevator’s restriction, opening the way to the 10th floor and the conclusion of the mission.

Silent Hill: Townfall guide

However, obtaining the card is only half the challenge. To print a new access card, Simon needs Richard’s employee ID, which means the player must first locate and open the right box on the stage. The case codes grid — assembled from two halves hidden in the waste bins of the security and maintenance rooms — reveals every box’s access code, but opening a random box will cost Simon HP. The player must open only Richard’s box.

Identifying Richard’s Box

To determine which box belongs to Richard, players should walk onto the stage and collect the Box ID’s and Names document from the lectern. According to that document, Richard is number 36, placing him in the third row from the stage and the third box from the right. The case code grid then supplies the exact code needed to open that specific box: 486.

With Richard’s employee file in hand, Simon returns to the security computer and enters Richard’s employee ID — 00007820518 — to print the level 10 access card. Armed with the card, he can finally board the elevator, ascend to the 10th floor, and complete the “Inside CEG HQ” mission.

Looking Ahead

Completing this mission advances Simon’s story within the post-apocalyptic Silent Hill setting, where the tension between stealth, survival, and horror defines every corridor. Players who stumble on the lockbox puzzle or misread the whiteboard pattern will want to revisit the maintenance room and stage, as both the code and the box selection are essential to progress.
