Not far from the castle, a round dark purple portal suddenly appeared in Towers 505. It looked ominous and soon lived up to its appearance as monsters of all shapes and sizes climbed out of it. This whole horde moved straight along the road straight to the castle gates. It is necessary to stop their advance as quickly as possible. Install special towers along the road on which soldiers with guns will be placed. The first towers will fire arrows, and as the attacks increase, you will gain access to more powerful towers, including magic ones in Towers 505. Your task is to place it correctly so that the army of monsters melts as you move along the road.
