Blind Fool 30 score.
Deactivate all Mosquitoes in a squadron except the Leader.


Mosquitoes can be spotted in the middle of Level 4, and the game has a warning you about them so you will know when they first attack. The leader is larger in compression than the rest and when you shoot it all of the mosquitoes will be disabled for a few. Just shoot every other mosquito making sure not to shoot the leader and done.
