The work is devoted to the study and improvement of the design, development, and testing of video game storytelling. The existing practices of writing and keeping up-to-date scripts for interactive works have been studied. The definition of a scenario prototype and requirements for its form are formulated. An idea was put forward about the efficiency of automating the creation of a scenario prototype in the form of a generator tool. A vision of such a tool has been drawn up. The impact of such a tool on development order is presented. Implemented a tool component and conducted an experiment that proves its effectiveness with an example such as generating storyboards from the text. Plans for future development have been formulated.
