And now the situation has changed, since the tower has changed the frequency of the energy and made it dark. As a result of this, various monsters, terrible creatures, etc. now appear around. You have to take the path of a chosen warrior who is ready to make every effort to achieve salvation. He is ready to fight using a katana and will try to unravel all the secrets of the black tower. Considering that dark energy turns the entire environment into poisoned lands, from where monsters and demons appear, you can only fight your way forward.
