Deadstorm Pirates

You must play through the entire game on single player mode and get rankings of "S" in each level. This does not have to be done in one playthrough as it saves your scores and displays them on future plays. To get an S ranking, you must get as many points as possible, complete challenges as quickly as possible and take as little damage as possible. Also look for treasure chests, barrels and other destructible items in the stages as some contain items that give you score boosts as well. Try to play on Normal difficulty if you are having problems as it seems like "S" ranks unlocks a little easier. Once you achieve an "S" rank on all the stages, the trophy will pop!
