The problem of high and increasing cost of video game development is considered, and to solve it is proposed to apply procedural content generation, which will reduce development costs.

The work is a part of a large-scale research on automatic prototyping of video games and is devoted to the processing of game scenarios, i.e. natural language texts. It is proposed to extract the necessary entities from the scripts and pass them to further steps of the algorithm, which will generate game resources based on the textual descriptions.

There are several publications devoted to game text processing, in which several different structures for storing the extracted information are proposed. In this paper we propose a universal format that is suitable for processing the text of any video game and allows to create a corpus of texts for use in further research and automatic generation of game prototypes.

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.

The description of the architecture of the tool for generating a scenario prototype from the text outlined in this paper is described based on the existing solutions.

We formed software requirements and developed prototype of the tool that illustrating the basic principle of the user's work with the application.
