Hey all,

I understand that L4D needs the online STEAM application to run. Now, if I get a used copy from someone who doesn't want it anymore, will I be able to install and play that? Or will the Online STEAM thing see it as being used again and not allow it to work?

Please excuse my lack of online-game-knowabout-ness....

Thanks,

Matt!

One CD key for Steam account. If the person you get it from has already played it, then you cannot use it. He cannot transfer it, either.

That's what I thought.. Thanks!
