As I went into a hallway two grenades come bouncing my way off of the wall in front of me, a guy then jumped out and preceded to mow me down in two seconds. There is no way this guy saw me coming since I was heading in his direction and I couldn’t see him. After I died I followed his character and he was hiding behind stuff then suddenly hopping out knowing exactly where the enemy was and from behind. I’m pretty sure he was in direct chat with a guy in the match that lost and was following others and talking him on to targets. LSS is so frustrating.
