I have finished this game 4 times because of a reason (acctually not). It was a great pleasure to play this magnificent zombie game which has 3 things to be considered as "magnificent" and these three are story,smooth gaming experience and the feeling that it gives.
When taking the story into account, it was kinda deep, continuing and gives you the chills of what you expected. However I think the story is a bit short besides the following DLC because it has a huge map and a different story line that follows the normal game thats why its called the following (play this DLC its good to play after finishing normal).
Observing gaming experience, it was amazing. This game has one of the best parkour mechanics to run accross the map and also it has skill lines that is not silly but logical. After finishing the game please try to realise what you were, because when you think with the time you have spent on game and in the story itself, it will feel like " Yeah the character is improving (or the gamer itself)". There is also a reason to play again such as the option that will be shown after finnishing the game and it is new game plus which is acctually the same game but with extraordinary diffuculties and prizes.
Also I should mention the feeling that it will give you. It makes you feel the environment and the story so sometimes such as nights, its horrible (in a good way)
If there is a competation among all zombie games, this game should be in top 3, and my points for story, gaming experience and the joy that I had are 8,5/10 , 9/10 and 10/10 respectively. Thank you Techland!
