What's the difference between the paid version and the free version?

When you purchase the paid version of the game, you'll be provided with a beginner pack that will be sent to your inventory. The beginner pack will contain food items, equipment, and medicine to help you start your game. The pack will contain the following items:

x3 Water Bottle

x3 Canned Food

x1 Military Boots

x1 Military Pants

x1 Military Body Armor

x1 Military Helmet

x1 Pump Shotgun

x2 First Aid Kit

Other than the pack, there aren't other differences between both versions. They still have the same content and it's entirely optional to get the paid version.
