Marvel’s Wolverine, developed by Insomniac Games and available only on PlayStation 5, has received mixed reviews from critics but seems to be popular among players for its intense and graphic combat style. The game blends fast-paced action with quieter moments that are key to moving the story forward. One of these moments occurs when Wolverine sneaks into Shiro's apartment to gather important clues. The first part of the apartment is relatively straightforward, but the second floor might be more challenging for some players. After exploring all interactive items, players may come across a code lock in the dressing room. This particular lock is different from others in the game because the code cannot be found simply by looking at fingerprint impressions left behind. The answer lies in Shiro's collection of manga. Most of the series are neatly arranged, but one volume is out of place. This misplaced book holds the key to solving the puzzle. The code consists of four digits, which can be found by noting the numbers of the four slightly raised volumes. Once identified, players must enter the numbers in the correct order to unlock the door. For those looking to progress more quickly, the code is consistently 1-9-2-4.
