Hey guys. I've been playing Conviction for a couple of days now, and for the most part enjoying my time with it. I've gotten all the Vanish and Prepare & Execute Challenges, and I'm relentlessly close to finishing the Splinter Cell Challenges as well. However, this pesky challenge that I mentioned in the title of this thread is escaping me for some odd reason. I've successfully performed the action the challenge requires me [shoot camera -> guard goes near camera -> shoot guard in head/CQC guard] to do numerous times on both the single player campaign[on Third Echelon HQ after the garage sequence] and in the Infiltration Mode. But for some reason, it doesn't want to give it to me. I was hoping any of you could point me in the right direction? Much appreciated.
