I bought the arkham knight standard edition digitally on psn but I don't seem to have the new missions or extra skins (adam west, and the justice league one) available to me. What's up with this? Do I have to order the crazy premium edition or something?

Kind of a bummer.

I didn't buy the digital edition, but I received a bunch of codes from Amazon for that stuff. Check your email.

might have download codes in your email, but also make sure to check on the AR challenges in the main menu for the missions. If you're referring to the scarecrow missions they are on their and are not actually side missions...
