This is what happens when Final Fantasy XIII-2 characters wear Mass Effect space suits.
The Japanese magazine Famitsu reports that the above pictures are part of a downloadable content pack that will bring armour from BioWare's popular sci-fi role-playing game to Final Fantasy XIII-2 next week.
Presumably there's some awesome in-game explanation for this DLC, like that Serah and Noel killed Shepard and took her clothes. And then they'll call it a paradox.
Update: As some commenters have pointed out, Famitsu also revealed DLC packs for Final Fantasy VI villains Ultros and Typhon, both of whom will be colosseum fights. Beat them and you can add them to your party. Octopus fanfiction optional.
