 Depending on the actions taken during gameplay by the players, two possible outcomes can occur during the final boss sequence; If Jagula is defeated during this battle but Lucia is not rescued, it will automatically trigger the bad ending, forcing the players to restart the game from the beginning in order to achieve the good ending by fulfilling certain conditions.According to former Toaplan designer Junya Inoue, "Ghox" was initially envisioned to be a vertically scrolling game but due to hardware issues, the project was retooled into a single-screen game instead.The game was released in arcades worldwide on November 1991.
