Forum:Arrival Import: Please Help

So I downloaded the Arrival DLC for Mass Effect 2, and I heard that it directly explains the beginning of Mass Effect 3 and why Shepard is removed from active duty. I decided to wait until after finishing the campaign of ME2 to play the DLC so that the events would seem to occur in order. Does this mean my completion of Arrival won't be included in an imported save to ME3? Also, does it matter whether or not the information is imported (does it have any effect on story, conversations, etc...)?--WaffleKing110 (talk) 00:56, September 20, 2014 (UTC)
