When a group of respected scientists finished research on gravitational-unity modifier, they asked the engineers to build an awesome technology from it to help in construction, transportation and military. But instead the engineers developed what they called gravity zones – a means to traverse an obstacle course – just because it was cool. They measured their time running through the levels and competed with each other to see who was fastest. However, by the time Pete Spencer gets here, the place has been abandoned. But the tech is still in place and functional, so he is going to make use of it for his own little agenda.
