When images come together, the viewer starts to read a story according to their own perceptions. The actual motivation of the storyteller is to let the viewer create a story based on their own ongoing biases, then to instill an unexpected perspective to make them retrospectively evaluate the entire storyline they had created. Using the transmedia storytelling method makes the viewer feel immersed in the story so that they can reinforce the image of the story in their mind. That is why I am trying to find out: “How can we effectively make the audience an active part of the project and create a common ground, by using Transmedia Storytelling?” This thesis will support the alternate reality game that I have formed via trans media storytelling named “At First Sight”. The purpose of this research is to examine the impact of the project “At First Sight”, which is an alternate reality game developed through transmedia storytelling in the frame of this thesis. This thesis introduces the works of the artist group called Blast Theory and analyzes the relationship between these works and the At First Sight project. In this sense, Play the Life, Live the Game and Confession projects, which were realized by using the alternate reality game and interactive game installation, were also included in the scope of the thesis in addition to At First Sight. In this context, the process and development of the projects examined are explained within the framework of supported theories and audience feedback.
