Hello guys, i'm looking for a challenge lobby, preferably for free. I only need challenge lobby because i got legit to 8th prestige and i want to stay in 8th prestige. I want to pay you for it , but no more than 15$, because i got allready 2/4 of my challenges completed. Message me on XBL , gamertag is HFN DuBsTePz X. I'm appearing offline but i'm only the whole night. Thanks!
