Even if there were tools that can dictate what is AI-generated and what not, they’d have to rely on a pattern, or on an artifact from AI-generated imagery (which, as far as I know, does not exist), and that is what can be used as proof, not the result of the tool itself being used.

They’re not really DLCs, just cosmetic packs that you can get if you play for long enough. The actual DLCs are the seasonal updates.
