While I'm killing time playing on FB (waiting for region 11), I've downgraded all my weapons to open sights. It's kind of fun to play this way. I've been mixing things up, like shooting all predators except the one closest to you before he can attack, trying to hit extra birds after the final one, trying to kill an extra predator after killing the final one attacking, etc. Not a bad way to keep the game interesting. Thanks, Glu for making downgrading your weapons an option.
