I apologize for not answering sooner (or answering already but forgetting where 😅) I wasn't subbed to the topic so I missed this message. The first 2 are tied to Campaign mode, but I can't remember which difficulty (if hard, then you'd only need to get halfway through for both). For "Curious Browser", try looking in the Credits menu ;3
Again, apologies for the extremely late reply, I should try being a little more vigilant next time 👍
