Perfect Dark Beta:   Air Force One

There isn't much to say here.  In the beta picture there are crates on the ground.  In the final version picture, there are no crates. It would make sense to have crates in an air base, but it would also make it easier to sneak up on that first guard.  Anyway, it's just a minor detail, not having much effect on the level.
 
 
 
 

Now, in the final version, you can't get a Mr. Blonde here now.  There are only two, and they stay next to Trent Easton, until you kill them.  Maybe, you were attacked by Mr. Blonde clones instead of Trent's goons, who you have to fend off now.

The cockpit of Air Force One has remained completely unchanged.  Except, you were equipped with a Dragon in the beta version, but it's probably a cheat, the dragon has infinite ammo as well.
