EA app DLC compatability with Steam base game
I bought Titanfall 2 Base Game through Steam and I couldn't find out if the EA app dlc would be compatable. It says I have access through Steam so I'm not sure if i should buy through the EA app (it has a better discount)
UPDATE: I found out I had a R-201 skin bundle on EA that I could still use, I bought the DLC and they are compatable.
