Social　engineering　attacks　target　people　who　lack　awareness　of　security.　These　attacks　have　become　increasingly　threatening　to　modern　software　systems,　which　rely　heavily　on　human　interactions.　Recent　studies　propose　to　conduct　serious　game-based　security　training　against　such　threats.　However,　it　is　challenging　to　simulate　real-world　scenarios　in　serious　games,　making　the　training　less　effective.　In　this　paper,　we　introduce　Security　Awareness　Adventure,　a　novel　social　engineering　serious　game　that　allows　participants　to　play　the　role　of　attackers　and　realistically　experience　the　social　engineering　attack　process　from　the　attacker＇s　perspective.　Our　game　works　with　state　transition　models　to　realistically　simulate　stakeholder　interactions　within　specific　scenarios　and　to　capture　stakeholders’　alternative　behaviors　using　a　branching　system.　To　evaluate　our　game＇s　effectiveness,　we　conducted　an　experiment　with　41　participants　and　a　real　social　engineering　security　scenario.　The　experimental　results　show　that　our　game　can　effectively　improve　the　learner＇s　security　awareness.　©　2025
