We were playing chromehounds last night in and out of matches as the normal. We launched a mission got in to the breifing room, 3 out of the 4 were in the room when live enemy showed up no big deal. The next thing actual pissed me off The fourth person to join was not a squad member it was a member of the other squad in our room. At this point it was WTF is going. How could a member of another squad get into our room, to but our four member could not get in after that guy left .
