I'm getting more and more excited about this game. Since there's been pretty much no talk about it here, here's some of what I can remember about it off the top of my head:
-Based on a Russian book of the same name, by author Dmitry Glukhovsky
-Takes place 20 years after the nuclear blast. People live in the metro system in Moscow (which in reality is designed to house people in case of such an incident)
-Different stations are different towns, and all have unique politics and attitudes on the situation. Some are devoid of human life altogether.
-It's sort of a survival horror FPS
-It's relatively linear, which the devs see as a good thing because it allows them more control over the pacing and storytelling
-Most guns are pieced together from spare parts and use homemade ammo. Pre-blast ammo is more powerful, but also serves as currency.
-You have to wear a gas mask when on the surface, which needs it's filter replaced every so often or you'll choke to death. Also avoid letting the mask get damaged, or you'll need to find a new one.
-Your watch shows you how hidden you are, and shooting out lights and such helps you stay in the darkness. (the watch is visible on your left inner-wrist as you hold your gun)
-The game has zero multiplayer. The devs feel that the fiction and storytelling are what the game is about, and it doesn't need a MP mode using up valuable development resources.
