You are NUX, sole survivor of the Nexon warrior tribe. The evil Silthax has invaded your home world of Nexolus, devoured your fellow Nexons and stolen the sacred power crystals from your village. Legend states that these crystals contain the power of life itself, and have protected your people for an eternity. They may even have the power to reverse the damage that the Silthax has done. With your home in ruins and only your ship and your trusty blaster to protect you, here begins your final mission. Hunt down this vile creature, rid the galaxy of its evil and recover the power crystals!
