In the project practice of garbage besiege, I explored the relationship between the city, people and garbage. Focusing on the issues of garbage classification and microplastics, I tried to combine VR, real space and video design to build a fantastic narrative experience. Through the process of exploring this fictional world, the audience gradually realizes that under the guise of high technology, people will believe in the illusion of perfect coexistence between man and nature, but they do not know that they are already under siege. Using such a gamifed interactive narrative to criticize people’s unrestrained use of the environment in the name of science, the final consequences may feed back on humans.
