During the Disguise mission in Judgment there is a locked Warehouse door. This Judgment Warehouse Door Combination Guide will tell you exactly where you can find the code to unlock this door as it’s hidden away during an earlier objective in this mission.
Before the mission you get to choose either attack entry, window entry or disguise. If you choose the disguise option you will get the opportunity to enter the building in a disguise, prompting a few interactions and investigation sequences.
Judgment Warehouse Door Combination Guide
When you enter the security room, after you’ve found the blueprints and the 3rd floor key, check the wall with the server-like objects and telephones. There’s another 4 digit code here. For me it was 8919, however it may be different in your game. The location you find it should be the same.
Make sure you investigate this clue then when you reach the warehouse door upstairs, it should tell you that you have the code. Then simply enter it in.
