From developer it seems mainly they made the survival aspect harder (item deteraition and radiation) with the added bit of movable+multi camp to counter that.
It also works and runs apparently a lot better with less issue.
If you like this sort of game, you gotta try Rebuild 3: Gangs of Deadsville. It's a fun and challenging city building, strategy survival game. Ah personal challenge for ya: Try to get the True Cure Ending! Good luck!(it's pretty hard to get)
