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 slot 41 is turned on, the process proceeds to S13, and a character designation image 60 for designating a character participating in the game is displayed on the display unit 13 as shown in FIG. Display. When the player designates a character participating 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.
To be displayed.

Subsequently, in S15, it is checked whether or not it is a single play. If the one-player start button 42 has been turned on in S15, the single-player mode is set, and the process proceeds to S16. If the start button 43 for two players has been turned on in S15, the process moves to S29 to execute the processing in the two-player mode.

In the next step S16, it is checked whether or not so-called accumulation shooting in which the firing button 17 is pressed for a predetermined time as described above is performed. When the firing button 17 is pressed for a predetermined time, energy is charged in S17. If a so-called accumulation shooting operation is not performed in S16, a bullet (underwater missile) having a normal attack power will be fired. Next S
At 18, the player operates the release button 17 of the operation handle 15.
Is turned on / off to determine whether or not the underwater missile has been fired toward the target. In S18, when the player turns on / off the firing button 17, the display unit 1
The wake of the underwater missile 65 is displayed on 3 (see FIG. 6).

Then, in S19, it is determined whether or not the launched underwater missile 65 hits a target (enemy 1 or enemy 2). In S19, when the underwater missile 65 hits the target (Enemy 1 or Enemy 2), the process proceeds to S20, where the target damage according to the type of the shot bullet is calculated, and the target state according to the degree of damage is calculated. It is displayed on the display unit 13.

For example, when a normal underwater missile 65 hits a target, the hit shark repeatedly hits the target,
As shown in FIG. 10, when the charge bullet 75 that has made a so-called charge shot hits the target, the target shark disappears, and two players perform so-called charge shooting almost simultaneously in the two-player mode. As shown in FIG. 11, a strong charge bullet 77 whose attack power is increased several times as compared with the normal charge bullet 75 is fired, and an attack image is displayed with light or the like stronger than the charge bullet 75, and surrounding sharks are displayed. All disappear.

In the next S21, a score corresponding to the damage received by the shark 61 as a target is added. Then, S2
In 2, the added score Na is set to a preset first
It is checked whether the passing point Nb of the stage has been reached. If Na <Nb in S22, the process returns to S15, and the processes after S15 are executed. Also, in S22, when Na> Nb, the passing score N of the first stage
Since b has been cleared, the second stage is set and displayed on the display unit 13 in S23. Then, the above S15
Then, the process from S15 on for the second stage is executed.

In S15, if the start button 43 for two players is turned on, the process goes to S29.
Then, the processing in the two-player mode is executed. That is, in S29, the two-player mode is set, and subsequently, in S30, it is checked whether or not to perform the so-called pool shooting in which the firing buttons 17 of the operation levers 15, 16 are pressed almost simultaneously for a predetermined time as described above. Operation levers 15, 16
When the firing button 17 is pressed for a predetermined time, energy is charged in S31.

In the next S32, the attacking power (destructive power) of the charge bullet 77 fired from the charge time from when the firing button 17 is turned on to off is increased. Then, control goes to the step S18. In this case, in step S18, when the two players turn on the firing buttons 17 of the operation levers 15 and 16 and turn them off almost at the same time after a predetermined time, the display unit 13 displays a strong attack force (destructive force). A state is displayed in which a large charge bullet 77 is fired at all targets. If the so-called pool shooting operations by the two players are not performed almost simultaneously at S30, a bullet (underwater missile) having a normal attack power will be fired.

As described above, in the two-player mode, when two players make a so-called pool shot almost simultaneously, all the surrounding sharks can be eliminated. Moreover, like this 2
A player who plays two people rather than a single player because the simultaneous operation is performed by a player, and the screaming operation such as "Issenossetsu" or "Senow" is used to perform the shooting operation. Can play games happily.

In step S18, the fire button 1
If the player did not operate the No. 7 or the underwater missile 65 fired in S19 did not hit the target,
Proceeding to S24, it is checked whether or not the submersible vehicle 50 has been attacked by the shark 61. In S24, the submersible vehicle 5
If 0 is not attacked, the process returns to S15, and S
The processing after 15 is repeated. When the submarine 50 is attacked in S24, the process proceeds to S25, and the damage received by the submarine 50 is determined.

At S26, the damage received by the submersible vehicle 50 is counted, and the number of the shield gauges 6 corresponding to the number is counted.
Turn off 3 In the 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 repeats the processing from S15.
However, when the shield gauge 63 becomes zero in S27, it is determined that the game is over in S28.

FIG. 13 is a front view of the display unit 13 showing an example of the game image of the second stage. As shown in FIG. 13, 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 enemy. for that reason,
