Marvel’s Wolverine asks players to look past the obvious in Shiro’s penthouse, and the answer is sitting on a bookshelf where nobody would expect it. The game’s “Bad Blood” mission throws players off the rails for a stretch, forcing them to hunt for clues instead of following a guided path. One of those clues leads to the code for Shiro’s keypad, and it turns out to be a set of manga volumes sticking out from the shelf.
Logan finds the keypad on a closet during his investigation of Shiro’s apartment, and he wonders aloud why anyone would put a keypad on a closet. The answer is that the code has recently been changed, leaving seven of the 10 digits marked with fingerprints. That narrows the search, but it still leaves plenty of things to check around the apartment — a medical billing invoice, various objects — until the right clue comes into focus.
The Clue Hides on the Bookshelf
The manga on the bookshelf is the key. Players need to notice that the second series, with black spines and white writing, is arranged in a seemingly random order, with four books in the middle sticking out slightly from the rest. Those four volumes are numbered 1, 9, 2, and 4.
Turn around and enter that code to reveal a secret room behind the closet. The secret room is the reward for finding the right combination, and it opens the path forward in the mission.
Why the Code Is Hidden in Manga
This is a clever clue, but it also feels oddly specific for a mainstream video game. Most games hide codes behind something memorable — a phrase, a name, a number that means something to the story. Marvel’s Wolverine goes smaller. It hides the code in a bookshelf full of manga, and the volumes themselves are the digits.
The four sticking-out books form the sequence 1, 9, 2, and 4, and entering that sequence reveals the hidden room. It is a small moment, but it rewards players who slow down and look closely at their surroundings.
What Players Should Know About Finding the Code
If you are playing Marvel’s Wolverine and you hit the Shiro keypad puzzle, the shortest path forward is to scan the bookshelf. Look for the manga series with black spines and white writing, and pay attention to which volumes stick out from the rest. Once you have identified volumes 1, 9, 2, and 4, the code is yours.
Players can also try the medical billing invoice or other objects around the apartment if they want to test their luck, but the guide confirms that the manga series is the correct answer.
The Mission’s Investigation
The “Bad Blood” mission requires players to investigate Shiro’s apartment, examining objects and solving puzzles along the way. The keypad is one of the hurdles, and finding the code is the step that unlocks the next part of the mission.
Once the secret room opens, players can head into it and figure out exactly what Shiro’s deal is.
