If you see a post that says " challenge lobby" don't go and fall for it! It's a scam just to get subs , rep , 2 day trails. Mw2 don't have those type of lobbies yet only ps3 have those type of lobbies but ps3 have infectable mod menus the most propular infectable menu is the cfg menu so to Xbox players if you want ur own mod menu come to ps3. To some of you who seem my last post ill host joka-_-modz menu for you all ;}
