The Cerberus came free with the purchase and lists as a separate download on my purchase list.
The other ME3 stuff is simply listed as free on PSN and did not show up on my purchase list.
Thanks. I'm seeing Mass Effect Arrival listed for $6.99. (Indicating that I haven't purchased it.)
Without spoilers, is it an essential DLC if I intend to play the story from One to Three?
It leads into Mass Effect 3 and without that you'll be confused about Shepards situation at the beginning of Mass Effect 3. Although all you really need to do is read a wiki or watch a playthrough of it. That's what I did.
