In a method for developing attractions in a shooting game system with which players can experience gun fights between the targets and players themselves. The shooting game system can be easily installed in a short period anywhere and game quality can be adjusted in the most suitable state. The method for developing attractions includes the steps of producing various types of targets by combining fundamental mechanisms, each of which is used for a unit operation; incorporating unified control equipment and peripherals in the produced target to make them a target unit; embedding the above-described target unit in a target unit case so as to serve also as an indoor partition and posts; and arranging the embedded target units in the designated rooms of the attraction hall. The method for developing attractions alternatively includes inputting information regarding the arrangement of the targets, displaying the arrangement on a screen, and the interaction between the targets and the players. This method thereby allows monitor and control of game quality.
