So if you play Single Player zombies and find the box, you would notice that the initial spawn point of the box is the same in EVERY game ONLY IF you keep restarting that single player game.
If you however, exit the single player zombie game and reload, the game will load a different generated, randomized gameplay environment so the box wont be in the same spot.
Not sure if you can understand me, but basically if you start a single player zombie game and find the box in the alley. Restart the game as many times as you like and it will ALWAYS be in the alley (as long as you do not exit that singleplayer zombie match).
