Both monsters and factions that inhabit the Zone are constantly interacting with each other. The previous S.T.A.L.K.E.R. games introduced A-Life — a living world simulating system. The reimagined version of this system, which we call A-Life 2.0, will control the state of the world and the behavior of characters and mutants, making the Zone ever-changing and truly alive. Countless events and encounters will happen every moment — even if you are not around to witness them with your own eyes.
With S.T.A.L.K.E.R. 2, we want every player to have a unique playthrough. It will take much more than just A-Life 2.0 to do that, as you are the author of your story. Putting aside the scale, the decisions you make will cause not only short-term outcomes, but influence the world itself. We are crafting an epic, branching story culminating in lots of different endings. You’ll have to make tough choices regularly — and be brave enough to face the consequences.
