A defense strategy in the style of dark fantasy awaits you in the game Dead Valley. Your task is to make the Dead Valley a death trap. The only road passes through the valley and a pack of monsters who want to approach the kingdom from the rear will move along it. The valley has always been considered impassable for large armies, so no watchtowers were placed there, but monsters can sneak through the narrow path. It needs to be made impassable. Place towers, increase their level, and do not let monsters enter Dead Valley.
