Wolfenstein: The Old Blood is a prequel to Wolfenstein: The New Order. It is a stand-alone, 6 hour game. We see Blazkowicz to a mission trying to retrive the coordinates of Deathshead compound. Apart from the story, that lacks in some cases, its just The New Order. I dont say its bad, but you cant call it an innovetion. It still has that beautiful feeling from The New Order that you can play stealth or like a maniac. It presents us some new guns and new villains but it tries to bring zombies in the story. It is fun to play those chapters, to see the zombies burn and die, but it "kills" the story. It makes it less realistic, as a story, from his predecessor. For my score i was between 7 and 8, but i thought that The Old Blood was as good as The New Order at his gameplay but it lacks at story. So i decided to give a 7.
AND DONT FORGET THAT IT COSTS ONLY 20 EURO
