Gears Of War 3 Glitch Fastest Onyx Medal

IF YOU NEED ASSISTANCE MY GT IS ANIMOSITYY. I HAVE TONS OF MESSAGES FROM PEOPLE ASKING AND I WILL CONTINUE TO HELP. ALL I ASK IS FOR IS FOR EVERYONE TO LIKE AND SUBSCRIBE. I REALLY APPRECIATE IT. THANKS GUYS This is a glitch I found in Gears 3 horde mode to unlock the Onyx medal "Field Engineer" in less than 10 minutes! This will also give you the achievement "Award Winning Tactics" if its your first Onyx medal. Step by step tutorial: IMPORTANT: Make sure the Host is the one getting the onyx medal as I found host gets it much faster. -Horde Mode with at least 1 friend. -Rules: Difficulty: Casual - Starting Wave: 1 - Map Selection: Host Chooses Enable Mutators: No -Pick a map. I personally found Thrashball to be the best. -Kill everything + give host all money (Stand next to aim (LT) and tap (B). -Host builds a turret. -Friend gets on Turret (X) and shoots (RT) non stop. -Host stand next to the turret and tap (Y) as fast as possible. -Repeat as needed If you have any questions please feel free to ask
