Stellar Blade: Lost Ark passcode puzzle and escape guide

June 23, 2026 - 19:39

A tricky puzzle in Stellar Blade has players stuck inside the Lost Ark, trying to figure out a passcode to unlock the exit. The sequence is not random, and the game does not hand you the answer directly. You need to pay close attention to the environment and a specific note you find earlier in the area.

The passcode is 0405. This number is not hidden in a terminal or a locked chest. Instead, it comes from a document you likely picked up while exploring. The note mentions a date, and that date is the key. If you missed the note, you might be wandering around the Ark trying every combination. The game expects you to connect the written clue to the numeric keypad on the door.

Once you enter 0405, the door unlocks, and you can proceed with the escape sequence. The puzzle itself is a good example of how Stellar Blade mixes exploration with simple deduction. It is not a complex riddle, but it forces you to stop fighting and read the lore. After the door opens, you will face a few more enemies before you can finally leave the Lost Ark behind. Keep your guard up, because the game does not give you a breather just because you solved a puzzle.
