Every now and then a screen shot appears during the loading that shows the Ghosts riding in a pick up truck in pursuit of a Santa Blanca cargo truck. Most notably there is a Ghost sitting in the bed of the pick up truck firing his weapon.
In gameplay, if a player gets in the bed of a pick up, he or she slides out the moment the truck moves and there's no "Passenger" button icon to push when standing at the tailgate.
Another screen shot, the very first one you see when you load into the world when starting the game, you see Weaver leaning on the buggy with his sniper rifle in a ghillie wrap. In gameplay, his rifle is not wrapped. Nor is it a option to wrap your own rifle with.
