To prepare for the onslaught of cryptids, use the blood runes gathered from the previous waves to build troop camps and defensive towers to fend off the incoming hordes. Choose from a range of different structures, with every one remaining for the rest of the run via an advanced save system, so you can leave at any time and pick up right where you left off. And remember, without an army by your side, your base will be quickly overwhelmed, so plan accordingly and create an impenetrable fortress that the forest dwellers will fear!
