Metro 2033 - 100% Uncut (PC) (hammer price)

First of all: A Hammer Game! It tells a story that can not even wish on your enemy. From a world that is possible despite of our day and age, still in the area.
Who's playing strategy shooter like is very good advice here. The books I do not know, so I can not judge whether the game is exactly the book holds. But basically it does not matter.
It has also been listed in my version of a small bonus

Conclusion: If you like strategy shooter and stories is well advised!
