CityBot-0720 is taken aboard the Proxima Space Station to explore the galaxy. However, when he's considered defective and thrown into the garbage pit to be spit out into the vacuum of space, he's not too thrilled. You take control of CityBot-0720 on his mission to travel throughout the space station he's trapped on, gather enough fuel, and blast him back towards Earth (and maybe steal some valuables along the way).
