The once peaceful planet Earth was turned into a gigantic factory b the alien horde. They have enslaved all humans to do their dirty work. Three women managed to escape and decided to help others out. So instead of running far away, they scavenged anything they can find. They created a ship from scrap metals they can find here and there and now they are back to fight the aliens and free humankind. At the start of the game, you will be asked to pick out which among the three you will be playing with. Each character has a specialty, whether it be POWER or SHIELD or a balance between the two.
