Yeah, you read that right. Final Fantasy XIII-2 will indeed be getting DLC in the form of Shepherd’s N7 armor from Mass Effect 3 for Serah and Noel to wear.
The news came from Famitsu, a Japanese gaming magazine, that showed pictures of the two characters wearing the armor. The DLC will be hitting next week (in Japan, at least) and will apparently have an in-universe reason for why they have it. If it means you can have Garrus in your party, I’m all for it!
