Along with the first trailer, there are several pieces of info to be disclosed:

• For the first time in the franchise, The Zone will be presented to the players as a seamless open-world environment — one of the biggest one to date.

With different behavior of characters and mutants, the Zone changes constantly. Every playthrough will be unique with lots of things happening every moment, even if the player doesn’t witness them directly.
