How do I unlock new scenarios?

I've played and won all scenarios available at the beginning of the game. Now the locked games remain locked - how do I access them?

If you mean the additional books and characters, those are available through purchasing the expansions. Like the physical tabletop game, each of the main expansions unlocks two additional books and two additional characters. The exceptions to that are the "Mouse and Variants" expansion which adds a character deck for Mouse and some variant cards for Harry and Susan and does not include any additional books, and the Ra Crossover expansion that adds Hank Walker, Alias: Ra as a crossover character from Sentinels of the Multiverse.
