As the image for advertisement, for example, an image or the like that simulates the appearance of the submarine 50 attacking the shark 61 is displayed on the display unit 13.
[0060]
In the next S12, it is checked whether or not a coin has been inserted into the coin insertion slot 41. When a coin detection switch (not shown) provided in the coin insertion slot 41 is turned on, the process proceeds to S13, and as shown in FIG. 4, a character designation image 60 for designating a character participating in the game is displayed on the display unit 13. Display. When the player designates a character to participate in the game from the characters displayed in the character designation image 60, the process proceeds to S14, and the start screen of the first stage is displayed on the display unit 13.
[0061]
Subsequently, a target selection process for the shark 61 displayed in the first stage is executed. That is, as shown in FIG. 7, since there are a plurality of sharks 61 around the submersible craft 50, the sharks 61 are selected based on the separation distance from the submersible craft 50 to each shark 61.
In the next S16, a priority is assigned to each shark 61 selected based on the separation distance as described above, or a priority is randomly set and registered in the main memory 24. That is, the registration number is set for each shark 61 such as the enemy 1, the enemy 2, and the enemy 3 for the shark 61 in front of the submersible 50. (Priority registration means)
Subsequently, in S17, the highest target (here, enemy 1) is displayed on the display unit 13. That is, the imaging camera 68 mounted on the submersible 50 captures an image following the movement of the highest priority target, and causes the display unit 13 to display the target. (Target tracking means)
In next S18, it is determined whether or not the player has fired an underwater missile toward the target by operating the launch button 17 of the operation handle 15. In S18, when the player operates the launch button 17, the track of the underwater missile 65 is displayed on the display unit 13 (see FIG. 6).
[0062]
In S19, it is determined whether the launched underwater missile 65 has hit the target (Enemy 1 or Enemy 2). (Judgment means)
In S19, when the underwater missile 65 hits the target (Enemy 1 or Enemy 2), the process proceeds to S20 and the priority order of the target is updated. For example, when enemy 1 falls down, priority of enemy 2 is updated to the highest. As a result, the display image moves on the display unit 13 so as to follow the movement of the enemy 2 (target capturing means: see FIGS. 9 to 18 and its description as specific examples).
[0063]
In the next S21, a score corresponding to the damage received by the target shark 61 is added. Subsequently, in S22, it is checked whether or not the added score Na has reached a preset passing score Nb of the first stage. When Na <Nb in S22, the process returns to S15, and the processes after S15 are executed.
In S22, when Na> Nb, since the passing score Nb of the first stage is cleared, the second stage is set and displayed on the display unit 13 in S23. Thereafter, the process returns to S15, and the processes after S15 for the second stage are executed.
[0064]
If the player does not operate the launch button 17 in S18, or if the underwater missile 65 launched in S19 does not hit the target, the process proceeds to S24, and the submersible 50 is moved from the shark 61. Check if you were attacked. In S24, when the submersible 50 is not attacked, the process returns to S15, and the processes after S15 are repeated. If the submersible craft 50 is attacked in S24, the process proceeds to S25 to determine the damage received by the submersible craft 50.
[0065]
In S26, the damage received by the submersible 50 is counted and the corresponding number of shield gauges 63 are erased. In next S27, it is checked whether or not the shield gauge 63 displayed on the display unit 13 is zero. If the shield gauge 63 remains, the process returns to S15, and the processes after S15 are repeated. However, if the shield gauge 63 becomes zero in S27, it is determined that the game is over in S28.
[0066]
FIG. 20 is a front view of the display unit 13 showing an example of a second stage game image.
As shown in FIG. 20, in the second stage, the giant octopus 70 is a boss as a target (target), and the eyes 71 and feet 72 of the giant octopus 70 are registered as enemies. Therefore, the submersible 50 performs an attack or a retreat operation according to the movement of the plurality of legs 72.
[0067]
Also in this case, the CPU 25 executes a control process as shown in the flowchart of FIG.
