I don't know if it's my computer, but after highlighting the entire group, or another character, if I want to select another character I have to click at least three times on him. It's like when I try to make my character to move right and my character just stand there like a dummy... only after several tries then he will move.
I wonder how they even aim with that thing on it. Looking throught the scope at this length, your view will be a small little circle and I don't think people will hold the rifle alittle back, just to place their head near the scope.
