The Stanley Parable weird blue hallway [duplicate]
Solution 1:
This blue hallway (which is not directly at the start) is another random element of the game. It doesnt bring much except randomness in the game. Kind of like when you begin the game again and have a straight corridor to the 2 doors room.
Solution 2:
I've read somewhere that this hallway was kind of a mandatory shortcut to unlock the Speed Run achievement.
