建议使用红色的武器，范围大威力也不错，再搭配H飞弹，敌人根本无所遁形打王丢个炸弹之后往上贴，很容易就能做掉王，如果不在乎分数的话建议用M飞弹，威力会增加很多

下面是英文攻略：
5 Bombs:
At the title screen, select "New Game" while the background is flashing white. If timed correctly, you'll start with 5 bombs instead of 3.
Hidden 1UP:
On stage 3, just before you reach the open harbour you'll see a blue box with a '?'. Don't shoot at it (if you have homing missiles or a wide-spread gun, let go of the FIRE key).
A tank will emerge from its base and run over the box, breaking it and releasing a 1UP.
Invisibility Mode:
Press CTRL During the takeoff sequence following stage 5. A textbox will appear in the lower-right hand corner of the screen; Type in 'go0gleypower' and you'll remain invisible for 20-30 seconds of stage 6.
Grab the Ruby just as you return to normal for another 1UP.
