Hello, This is the last achievement I need.
I been asking people in my friend list, and they kept saying that it have to be earn in Lone Wolves. I kept telling them that they wrong, and I kept showing them proof but they don't listen.
Now, I need somebody to help me to earn this achievement in Rumble Pit, and I would thank you if you help me.
