You know, I noticed something a few days ago (which Bryan told me was old'd, but I think a lot of people haven't noticed this).
The music in Bunker 1 after the alarm goes off, and the music after Bunker 2 when you exit...should they have been flip flopped? The dead giveaway is that Bunker 2 regular and Bunker 1 alternate sound exactly the same. Accident or intentional by Rare?
