is interesting. Looks like it might be a screen-shot from the Leviathan DLC. That or you can get some funky new toys for your fish tank...
Almost certainly going to be the Leviathan DLC. Between the mined data files from the Extended Cut script having plenty on it (including references to an underwater portion of a mission) and the Leviathan's VA outing the project, and then now this, I'd say it's a safe bet we're getting this first.
