1. Step 1 : Immediately upgrade the aircraft to the full level at the beginning. Place another plane under the submarine, start eliminating props and place mines. At this stage, prioritize upgrading the mines on the left to clear the props.
2. Step 2 : After the prop location on the left is partially opened, continue placing turrets to clear the props on the left. Likewise, placing additional aircraft on the right enhances damage output.
3. Step 3 : Most of the props can be cleared by aircraft. We only need to concentrate on clearing the props that cannot be hit by aircraft and strengthen all the turrets online.
4. Step 4 : Pay attention to the presence of sailing rabbits, so be sure to place a few more missiles. In the final stage, you only need to increase the number of online turrets and increase the damage to pass the level.
