I think the rating of this game is unfair. As an immersive game, I think it's great. You are in a kind of Mars where your only contact with life are flashbacks, notepads and the Soviet Union anthem that sounds in some places. Nothing else. The rest is falling down trying to advance by places, without being difficult but without much help. And to go following the history. It is interesting. But if you look for action it is not your game.
