Its not working , neither i will think it will work again ...
To get nantonium boxes on SAS 4 you need now to pay coins , at least playing it on ninjakiwi , for me this hack its not worth anymore , it would need to be something brand new like get amazing drops of nantonium boxes while you play it , more chances of getting high levels of boxes dropping from zombies when you kill then .
That would fix the problem and no need to buy then on store.
Using the high level drops hack of boxes and money that still works very well , with a new hack to get only high level nantonium on the Map Pods that can be compleated on 2 minutes could be a very good way too of making alloy very quick .
But great great great would be the perfect hack .. make the weapon cost of money and alloy on the collections menu to drop to low prices that would reduce a lot of hacks that were made just to to have chances of good weapons .
If this was made there would be no need for hacks of box , ways to get alloy or even worry with money again.
