I think this game is something between DayR, Minecrafts and a random zombie apocalyptic games. It allows you to design and build vehicles or houses from scratch to the point where you can build the remote controlled suicide-bomber wheelchair to blow up pack of zombie squads.
The updates are now so far only available for the Day R Premium app, and not for the free Day R app (even though you have bought the premium through the Day R app). I guess it will be released soon in the free app, too.
This is what I got from support -
