I bought the Call of Duty game, but I was wondering if someone else could log into my Steam account at the same time, so that we can play multiplayer. Is that possible? Or do they need another account and therefore another game CD?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Steam will kick one of you off. Steam will see that two people are using the same account and will kick one of the two of you off. He needs to buy a separate COD account.
