It can be played by one person using two or more Heroes without changing the rules one iota.
If you want to play just one Hero against the Darkness, then yes. The game can be played solo. However, it requires a little tweaking to the Darkness AP and Bosses. We plan on releasing these tweaks as a pdf once the game is produced.
You'll be able to play the game completely with the base game. However, you'll be limited in how you populate the tiles by how many miniatures you have. A large 12" x 12" tiles can have two lairs spawning multiple creatures. Without additional minion miniatures, these tiles will ALWAYS need to be of two different enemy-types. With additional minions, you will be able to create a tile that is all Arachnid or all Orc (or all Skeleton, if we hit that stretch goal). More minion miniatures means more freedom for you to tell the story you want.
The Kickstarter system does not allow the editing of pledge level text after things have gone live. As stretch goals have unlocked we wanted, and thought we could, update the pledges to represent things have been added, we could not. The pictures are correct.
