This is not a movie, either comic. this it is really a game of action in first person, based on World War II. this first part includes 2 missions.
if you kill more enemies, you efficiency will be better, but the game is more hard.
I decided to change game-name, in order to avoid bad understood.
this game related with the world war II, and not another thing.
Now is more attainable to get efficiency 50%.
A great greeting. excuse my ingles.
