A lot of maps are available in the application with the title "Siren Head," the same as our map. But it's a completely different mod that adds a new entity called Boss, which is a unique mob that is very good at camouflage in the dark. It sounds just like a cat, and also has a unique look, so that the enemies will be unable to attack it.

The Boss entity has some abilities that no other mobs have. It can throw out a number of arrows at once, jump up to the air and into the sky, and also attack all other entities at the same time. You will need to take these abilities into consideration, so that it will be possible to survive in the game.
