Now, I obviously didn't use the glitch, in fact i cancelled the smoke that caused it, because using it is cheating, and I personally don't want to get banned. However, you can travel the entire distance of Omen's smoke. And, you can see enemies. Its like a UAV. How this glitch is caused im not entirely sure, but I'm pretty sure its switching between your weapons incredibly fast and opening the shaddow realm WHILE also opening the regular smoke mode. (All at the same time) Now if you come across this, don't use it because its cheating and you will get banned.
