This is a game that came out after Bethesda's E3 presentation. It's a mobile version of Fallout games, and it's addictive. The game is completely free to play. Only thing that you can pay for are the cases that you can find for free, but if you want more, you can pay for them. Inside these cases are weapons and what not for your vault-dwellers to use when attacked. That game has earned over 5 million dollars in the first two weeks since it's release, only from the purchase of these cases. This game is only available on iOS so far, but will be on Android this or the next month.
