If you want to download the free downloadable content for LEGO Worlds on the Nintendo Switch and don’t have a Nintendo Switch Online membership then you are currently out of luck. The content in question is the Mega DLC Showcase Collection Pack which is completely free for owners of the game. TT Games and Warner Bros Games are aware of the issue and has raised it with Nintendo Support as it shouldn’t be locked behind a paid membership.
Yes, yes I have!
