Made some unexpected changes to Boarding Pass. Added an irremovable turret here (The turret is behind the sandbags. It just didn't spawn when I was taking the picture because I used the wrong gametype). This area has always been neglected even in the map's version in Halo 4. The turret has given it more activity and makes it a very decent holdout location.
There is also a route now from the bathroom to the sweat turret to give the Infected more...
