Talk:Headshot Honcho

OK, my son and I went in to Sierra 117 to get the 15,000 points and the 10 headshot achievements. We enabled meta scoring by activating team scoring and activated 4 skulls (Thunderstorm, Famine & fog). We went through the level and scored 16,000+ points and each had well over 10 headshots but received neither of the awards. The skill level was set at normal. What gives?

Unlimitedguy5-You mentioned that you can kill the marines before activating the bridge, but where are you supposed to get a sniper rifle?
