When I first heard of this game I was quite excited because I love this World War I setting. When I started to play I thought this would be an adventure game during the war but, not connected to what was happening in the frontline. I was wrong. The story shows you how the war affected the life of regular people, so you get a great glimpse of what was happening in the western front. You will experience both sides of the war, the allies and the germans through some of the bloodiest battles in the conflict, like Verdun, Marne, Ypres, the Somme and so on. You will experience gas attacks, underground warfare, the first air raids, massive artillery barrages, yet as violent this may seem you are not encouraged to kill in this game. You rather knock the opponent down or make him run away, in fact the game fucus more on how friendship and kindness can prevail even during the darkest times.
The soundtrack does an amazing job creating an immersive mood.
The gameplay itself it's good, you have to solve multiple puzzles through the game that could be a bit more difficult. You won't get stuck many times during your playthrough. And you are not on the trenches all the time, the variation of locations is great and it works good after a level in a more oppressive environment of the frontline.
At the same time the game doesn't take itself serious, it made me laugh mostly during the dialogs. The dialogs are well done, they satirise all the spoken languages in the story. Most of the characters are compelling specially Walt, he's the best companion you can get!
Through most of the levels you can find various collectibles that provide historical information about the time period, there is so many information that you feel it is an interactive documentary.
So in conclusion, I definitely recommend this game but, I have to mention that once again to have a full experience we will have DLC... Don't get me wrong, the ending is good but, there are some loose ends in the story and well, it ends in 1917. So, I think Ubisoft will release some DLC for this. Not cool.
