The deep,touching and immersive gameplay will suck you in,you will play it even when your pc/console is off
Right from the start we fit right in the story.It is a great plot full with twists.Everyone will like the plot and how it turns around constantly as we are fighting through the tunnels of the Moscow's metro.Really everything is good;the weapons,the sneaking and stealth takedowns,the characters,the environment,the npc's and their stories,the life in these post-apocaliptic "cities" and the human nature that never changes.Not even nukes and aliens change our default brain switch which is to kill and dominate.You will need to try harder to pass through some places and objectives.Never in my playthrough i felt the game and the environment empty or...dead.It is like the game has a soul on it's own.
The only part from this game that I didn't like is the moral system and to a lesser extension the endings.The moral system is kinda strange.It is right and wrong about one same thing but that is subjective thinking,I don't want to spoiler anything but you guys like me will end up with the "bad" ending...which leads me to the second thing that bothers me.I liked the bad ending more than the good one!!Awkward isn't it?
But these are minor things to worry about.As I said you will be sucked in this game so much that you will play it in your sleep.
