Metro 2039 release date window, story, and trailers

What is the Metro 2039 release date? There are very few games that thrust you into such dire circumstances as Metro; unlike the occasional jovial nature of Fallout, this is a post-apocalypse with very little bright side. Survival is paramount, and there is no line that can't be crossed to achieve it. The latest in a long-running series, Metro 2039 is a first-person shooter that pushes the boundaries of the will - what will you do to survive, and what can the collective do to prevent total destruction? In this new entry, it isn't just the horrors of the outside that threaten you and yours, but a human faction, one whose idea of order looks a lot like control.
