Well I can't really help you, since I don' own the game, but have you tried the in-game options, something like "parental control" around there?
Those kind of games usually have it, nowadays.

But, hey, I've never heard of that title before! While it's the well known "slay-those-evil-German-bastards" all over again, it looks mighty nice!
Why do you want to turn down the effects - I didn't look to bloody in the video you posted?
