User blog comment:Callofduty4/Robert Bowling hangs out on Google+, reveals DLC info/@comment-4454520-20120323032051

Wouldn't there be a problem for people who haven't obtained the weapon DLC, such as them not able to play with other players due to them not able to use/pick up DLC weaponry. I would love weapon DLC but how would some problems be fixed to make sure people who don't have the guns still play with people who do?
