The precious HEARTS need rescuing! It’s up to you to build them a fortress strong enough to last through the terrifying, Alien-Monster filled nights. Drop blocks to build Robots that shoot lasers, illuminate the dark -- or even make more Blocks to build other Robots! So many possible combinations of Robots that every player's stronghold will be unique. And you're going to need all the base-building skills you've got because the Wild only gets tougher. Every. Single. Night.
