I dont download the day-1 digitals, but I wouldnt think you have to buy a $10 online pass since those only exist to deter people from using second hand stores and services. Um, just dig around the menus, it has got to be listed somewhere.
I downloaded the new army of two game and i got the theme and overkill edition content. But i didnt get an online passcode. If the game is purchased on disk it comes with it. Why didnt it come with the online purchase. $59.99 for the game now i have to spend another $9.99 for an online pass. Is this a normal thing?
No you don't.
ALL new games come with an online pass, have you actually tried playing online?
