The alphanumeric entry system within the historical building presents a specific puzzle for players. Solving this puzzle requires deciphering clues found within the game’s environment, specifically examining documents and architectural details located in close proximity to the locked mechanism. Successfully inputting the correct combination grants access to a previously inaccessible area, crucial for progressing the narrative and uncovering further secrets.
This interactive element serves as a gatekeeper, restricting access until the player demonstrates problem-solving skills and attention to detail. Its function extends beyond mere obstacle; it actively encourages exploration and rewards careful observation. The inclusion of such challenges is characteristic of the game’s design philosophy, which emphasizes psychological unease and rewards player investment in its intricate world. This type of interactive puzzle is a common hallmark of the survival horror genre, offering a brief respite from direct confrontation while simultaneously heightening tension.
