Naturally, there are a lot of unanswered questions surrounding the game, but some of them at least may have been answered thanks to an NME interview with Firaxis. Chiefly, the studio confirmed that Midnight Suns will not have any microtransactions. “This is meant to be a single-player tactics RPG,” creative director Jake Solomon told the site. When pressed on whether this ruled out cosmetic DLC options or similar add-ons, he confirmed ““Right, no. That’s not what we’re aiming for here.”
What this means regarding larger expansions or other forms of post-launch content is currently unclear, though. XCOM: Chimera Squad, the most recent non-Civilization game to come out of Firaxis, didn’t receive any post-launch content. While this doesn't indicate anything concrete with regards to the studios' intentions for Midnight Suns, it does suggest a precedent.
