Helldivers 1 gated a lot of weapons behind DLC.
I’d assume that this would be the same; but i guess micro-transactions are more of a thing than they were 5 years ago.

sounds a bit like “Long LIve The Queen”. Which I liked; but maybe with less humorous bad endings?
Though, I can’t tell if you play as the princess or the person slaying her? Guess I’ll find out if I play it.
