I'm going to throw the few cents that I have in the pot.
I've seen many things going on the Galaxy section, mostly exploits, but one glitch blew my mind off like a Black Widow with shields down.
I call it "The Shadow Connection".
It started out like a normal match on the Firebase Ghost.
After joining into this session, I found out to my surprise that I was alone. No other players were present or on the scoreboard.
I kept playing like normal untill I noticed that unknown names are popping up in the killfeed, I keep crashing into unknown invisible objects and the enemies spontaneously die.
What happend here is nothing I'm quite sure about, it was like two sessions have connected but not completely.
Like my lobby merged existance with an active session and that kept happening in intervals of 0.0001 nanoseconds.
Shortly said, it was the day I won a silver match with an army of ghosts.
