The story is based on the fact that the boy must save his sister, protect the city and kill a giant bloodthirsty clown. If you complete only 1 or 2 of the tasks, then the ending is sad. To meet the clown and get into the enclosed space, you need to go into sleep mode by clicking on the red ball. But the atmosphere there is bloody.
In the city it is less difficult, but you need to collect cartridges, first-aid kits and look for weapons. By the way, there is such a trick: you need to find the section of the episode where it says “save”, or a typewriter. This will help you start the adventure from the saved level. In the city, the monsters are not so scary, but at the military base…
You can do this by touching the red ball, back in the same way. Then the world acquires a red tint, new passages open, and some other details. By the way, people suffering from trypophobia, Death Park 3 is contraindicated. During the transition, the floor, and some doors, are covered with holes.
