Played El Karatina with only a Sniper Rifle. Mostly solo, although I was joined for a short bit by Goldfinger. I was trying to get the SNIPER medal which is 70% One Shot Kills with a minimum of 40 kills. I feel kinda screwed since after the first three levels of El Karatina I had 65 kills with 56 one shots and I didn't get an award. I did manage by the end of El Karatina Circle though. Here are some pictures of the highlights.
