Revealed a scant six months ago at E3, Metro Exodus showed that the franchise was going to take a dramatic turn: the open world.

And we don’t see much of it here, though there’s plenty that hints at the grander, more ambitious scale. The vistas, for instance, are the largest we’ve seen in the franchise. And then, of course, there’s the train.

It’s pretty much the entire crux of why it’s called Exodus as it seems to be the thing that enables you to leave your starting area of Moscow for the rest of the world in a Snowpiercer kind of situation. There will, however, be changing weather patterns based on the season, though it’s unclear how many variants of debilitating snow there can be.

It’s expected to release sometime in 2018 for the PlayStation 4, Xbox One, and PC.
