Topic: 100% Luigi's Mansion 3

I just finished my play through of Luigi's Mansion 3, and got my final rank from the rebuilt hotel. If I want to 100% the game, do I have to start an entirely new save file?

Someone back me up on this, you don't need to make a new file, you go back to the levels/floors with your existing game. I haven't finished the game yet, but in E. Gadd's lab, you can look at what you've got so far, and see what's missing. I'm sure someone else can flesh this out with more detail.

The only reason I ask is because when I go back to my save file after beating the game, it puts me at my last autosave, in the final boss arena.

@xslywolf no you just continue from your save so you can go back and collect all the missed gems, ghosts boos.

Thank you @1UP_MARIO !
