The game's background story starts off as Earth is about to be destroyed. Mankind loads spaceships with refugees and cultural artifacts. These ships crash on a planet somewhere. The ships' computers attempt to recreate the planet in the image of Earth, but due to bugs, they end up creating strange monsters. The game begins 1,000 years after the crash landing. You'll have to team up with the planet's native residents, known as Guardians, to combat the monsters created by your ship. The Guardians aren't too fond of you because of what your ship did to their planet, but they're willing to work with you in exchange for booze.
