This paper provides an overview of the intersection between (violent) extremism and video gaming, examining the current landscape, trends, and threats. Analysing existing literature and open-source materials, this paper discusses the types of games, platforms, and services that are vulnerable to this type of infiltration and use; particularly focussing on content, platform features, and overlaps. The paper also examines a number of recurrent themes, including: ‘radicalisation, recruitment, and reinforcing views’; ‘community building and strengthening’; and ‘extremist online ecosystems’. Thereafter, the responses to (violent) extremism from various platforms will be explored, before reflecting on current challenges and future considerations.
