 The player must prevent the Sporg from completely powering the jumpgate . While completing the task , the player encounters several warships that attempt to protect the jumpgate . These enemies are indicated on the radar with a dynamic set of coordinates that turn from white to red as they approach . If the player succeeds , the jumpgate breaks and the level is finished . Otherwise , the Sinistar will arrive through the activated jumpgate , and the player must defeat it to progress further . The player has six different starships to choose from , as well as eight power @-@ ups and nine weapons to destroy the mining ships and the Sinistar . The most powerful weapon is called the <unk> , which is designed to defeat the Sinistar , although it can also be used to destroy the jumpgate . The player obtains <unk> by harvesting crystals from asteroids in the same way Sporg do .
