Sorry about your voice bud, hope it comes back soon. Your video's will give me something to do during lunch this week, so thanks. :)
I do not recall how far into the game this room was, probably about halfway to 3/4's of the way through. It's a typical office where the door is locked but the windows are broken. You'll be lured in by the ever so common e99/ammo boxes/etc. I think even a weapons tech case.
I do remember that the room is in a hallway that turns right at the end, the office is on the left in that hallway, before it turns right.
And its in the modern timeline, not during a rift to the past.
