Build the maze. Hold the line.

Spirit is an energy that runs through the world. Creatures exposed to it change — a wolf becomes a Dire Wolf, then an Alpha. When enough of them gather, they move together as a Beast Tide and descend on human settlements.

You defend the settlement’s Town Hall. Beasts enter from the top of the map and fight their way down. Every wall you raise and every Tower you place decides the route they take — and how long they spend under fire.
