Metal Gear Solid V: Ground Zeroes already brings a lot of new elements in the Metal Gear Solid series and a lot more will be implemented in the following episode, Metal Gear Solid V: The Phantom Pain.
The first big change will be the open-world environments where you will be able to freely progress in each one of them. In addition to this, there will be a changing weather system feature which will put you through different types of weather during your adventure. The AI will be hugely improved for a more realistic gameplay experience, no matter how you decide to play; sneaky or brusquely.
You will also be able to have access to a much more improved configurable Mother Base and a brand-new app will also be available to accompany you during your new Metal Gear Solid quest.
