Along the way, they encounter Shot Bus Gus, a mysterious prophet who seems to have a unique ability to control the beasts with ease. He informs them that they are headed towards the big city, where they will have a chance at defeating the creatures once and for all.
As they travel through the sewers, they also come across Jean-Claude Seagal, a skilled martial artist who joins their fight against the monsters.

With the knowledge they have gathered, they prepare for a final showdown to save the world from the deadly creatures. The group must summon all of their courage and strength to fight to the bitter end, in order to ensure that the monsters are destroyed once and for all.
