This game made me question the face of mankind. It's going to be hard to find such realistic game as Metro 2033.
Turned off lights, set the difficulty on Ranger Hardcore, turned volume up.... ---> possibly one of the hardest video games I have ever played, but definitely one of the best.
The realism level on this game is jaw-dropping. People act naturally, atmosphere is amazing, you start to care about the protagonist and the events that happen.
It may look like the first part of the game is already challenging and the main character gets into every possible kind of trouble. You will get stuck in dark tunnels where mutants are roaming, you will run out of oxygen on the surface, assisst to the ugly shade of war between russian powers, at a time when they should help each other survive and many more.. But after the first half of the game you will realize all those things were just a preparation for what's coming.
I recommend you to play with Russian voice acting (and English subtitles), this is how the game was intended and it adds a new level of immersion. Also, if you have the guts, try playing on the hardest (and by far the most realistic) difficulty, like I did. It will turn out as a very rewarding experience.
Pros: +The most realistic FPS I have ever played, speaking of the accuracy with which the mankind was represented in a video game;
+ The attachment with the main protagonist;
+ The Ranger Hardcore difficulty;
+ Excellent atmosphere and voice acting;
+ Incredible graphics;
+ Replayability, for the other ending;
Cons: - Some bugs can be game-breaking and require restart of the level;
- Only a few Metro stations, in which you take a break from the harsh tunnels and surface;
- The AI is sometimes pathetic;
Overall, this game is a MUST for those who enjoy a FPS with a different approach than most others; a FPS where you are not a heavily-equipped soldier, but a normal living man in the stations whose destiny is about to be accomplished.
Personal rating: 93/100
