I've searched just about everywhere, and I can't seem to find what I need, so here we go:
I've just started the game, and I'm currently building my thirteenth shelter. I've still only got the 4 preppers the game came with, and no more have come to join my bunker. I never get VIPs come visit (I have only one time in the past three days I've been playing), and I haven't gotten the "big gift" from the delivery men at all. I'm not sure how to get friends that I've added into my bunker either.
Is this all because I've just started playing, or am I doing something very wrong here?
Something is very wrong. With the most recent update, preppers should show up 1 every 24 hrs for each separate shelter with an open slot. They will wait until you open the game if you are not playing at the time they are due to arrive.
If you have accepted friends you haven't already added as preppers to your bunker: you should be able to click on a shelter with open slots, the top choice is Move in a friend, click the blue "Move" button, wait a while, when choices of available friends pop up, select one. It should be simple.
If neither of the above are working/happening, go to G5 entertainment's web site and open a request.
About the delivery guys, you can reset who shows up first. If you like who is first, always leave him in first place when closing the game.
If you don't, close the game with NO delivery men showing. Then, double click the home button to pull up the app activity list. Click and hold the Prepper icon, when the icons start shaking, click the red "-" and the Prepper icon will disappear. You have just reset the game. The next time you open the game, a new set delivery men with show up. Keep doing this until you find one you like, then close the game with that guy in first place and he will be there next time you open the game.
Good Luck!
