Deadstorm Pirates

This is story related and can not be missed if you finish the game!

This must be done in ARCADE mode! If you are having problems with it, then set the difficulty level to Very Easy. If you are still struggling after that, then keep starting a game and let yourself get killed immediately so you get game over as it will then give you get 2 additional credits for the next playthrough on that difficulty (they accumulate after each attempt, so just keep going until you feel you have enough to get you through the level).

Boss:

The boss of this level is two enemy ships. You are given cannon weapons to attack them, but they need to recharge between shots (takes about 2 seconds to do so), so make sure you watch the enemy ships as they will fire cannons of their own at you that you must shoot down. After you destroy the first ship, repeat the same method for the second one until it falls.
