Narration in Side Effect made in a non-standard approach, talking about global environmental problems in the form of a game. In open spaces for free exploration, immersing you in a variety of natural biomes of forests or fields, you need to move around and observe the terrible consequences of human activity on the planet. All places are contaminated with plastic bottles, bags, paper and glass. The smell of smog is thick in the air, filling the natural beauty of the natural environment where small animals live and new plants sprout.

In the process of passing Side Effect, you will have to actively interact with the world around you and collect garbage. Collected waste elements must be sent for recycling to eliminate catastrophic consequences. During a long adventure, you will get to know a lot of animals that live in these parts. The protagonist gets the opportunity to communicate with the animals and learn their individual stories, imbued with the difficulty of the current situation. Having made friends with the inhabitants of the forest thickets, new friends come to help in cleaning up the territories and provide useful support. Moving along the storyline, you have to gradually figure out the beginning of the pollution and help the flora and fauna survive in the conditions of a total garbage apocalypse.
