When I went to check out the co-op play option but it says that I haven't purchased the Online Pass and therefore cannot use it. I know that online passes have become more popular in the past year and often require a separate purchase if you buy the game used/secondhand, but so far the precedent I have seen is that you get an online pass if you purchase new.
I have purchased Saints Row: The Third brand new (the Platinum Pack even). It didn't seem to come with any separate Online Pass code that I can find in my box. All I had was the code for the Professor Genki DLC.
Do I have to purchase the Online Code separately even though I have a new version of the game? Is it possible my box was just missing the code?
