U-boat Annihilator

Destroy the submarines below your destroyer and avoid being hit by rockets.

Your objective is to survive as long as possible against the never ending flow of submarines. You drop depth charges at the submarines to destroy them, but be aware of the rockets they send at you. You can only be hit 3 times before the game is over. As you get more score, the submarines get more aggressive and your boat gets faster and can carry more depth charges.
