PUBG Mobile is a battle-royale genre game that is very popular among generation Z. Since PUBG MOBILE was published, in West Papua Province, especially Manokwari Regency, there has been no specific study examining the factors that drive the adoption of PUBG MOBILE among generation Z. Therefore, this research was conducted to find out what factors influence generation Z's decision to adopt PUBG Mobile by integrating the TPB model.  Therefore, researchers feel the need to conduct research on what factors influence generation Z's decision to adopt the PUBG Mobile game by integrating the TPB model (intention and behaviour) with external variables, namely peer influence, external influence, facilitating conditions, challenge and interactivity as measured through partial least square (PLS). From the results of this study it was found that these factors are peer influence, facilitating conditions and interactivity have a significant influence on intention. Intention has an influence on behaviour. External influence and challenge have an insignificant influence on intention.
