-The miracle workers on both Dr. Evil and Austin Powers side pushed the point back! So that it takes longer to get there.
-They think that they fixed the door sensors. Very new tech so you never know
-For some reason there is a shed with a truck parked there now.
-They demolished the upstairs sniping deck and redid all of the transition rooms.
-They took inspiration from the man who was kicking all the health kits and put them in different places (except this time they're not breaking a law)
-They used a different material on reds side for metal roofs (It was probably cheaper and in less demand.. cheapskate)
And thats about it. Happy new years and enjoy the rest of your day.
