As they were with Mass Effect 3, the multiplayer maps of Mass Effect: Andromeda will be free. Bioware GM Aaryn Flynn confirmed the news after being asked by a fan on Twitter:
It was also confirmed earlier in the year that there would not be a season pass for this game, although that didn't mean that a potential expansion would not come up for sale. Either way, good for Bioware for not charging maps considering that's about the most commonplace DLC charge out there. Mass Effect: Andromeda launches March 21st.
