A glitch found in Modern Warfare 3’s latest DLC , Black Box, has Infinity Ward calling cheaters to beware or get banned. Here’s the warning per Robert Bowling: “There’s a glitch in Black Box that allows you to get under the map. Fix already in the works, out by Friday. Don’t exploit, we’ll be banning.” That’s all really. Don’t use the glitch to your advantage, and a fix will be issued by Friday.
