I need a partner for the Dead Center Campaign on Realism mode. I want to get the achievement but I need my partner to have plenty of time on their hands.

I also need my partner to be very good at this game by knowing what to do, and following my directions.

I've done this campaign by myself over a dozen times, but can't beat it without a partner.

Just follow my directions, don't rush or do anything silly and we'll finish it.
