You can fly! Flying is fun, swooping and soaring, going as fast as you want over, under, around and through things. You point in any direction and your anti-gravity rings fly you that way. But flying is also very dangerous! Touch anything, at almost any speed, and you're dead-- splat! Be sure you've gone to episode 0, Ball Game, to learn to fly first! It's free! The time is the 26th Century. The place is a 'flyland,' an adjustable-gravity, half-kilometer-square surface high over an ocean, far from any land. Most flylands, unlike this one, were once the playthings of trillionaires, who were usually enriched by mining the wealth of the solar system using anti-gravity. The inventor of flylands, and a-grav technology itself, also made an immense low-gravity space colony, but it became diseased, forcing tens of thousands of gravity-weakened refugees to invade the only places they could survive-- adjustable-gravity flylands. That invasion was the First Flyland War, which the trillionaires lost in a day. The Second Flyland War soon followed but the trillionaires lost again because of their unmitigated greed. However, the refugees were left defenseless thereafter. Now the Third Flyland War, The Revenge of the Trillionaires, is beginning and the otherwise helpless refugees have only one single individual to defend them against the combined robotic might of a hundred impossibly greedy and angry trillionaires-- you. Your only weapons are hand-thrown, ultra-hot flares, great for wrecking robots if you can get close enough to hit them. Robots are mighty weapons. But you have creativity-- and... you can fly! This flyland, Not Yours Mine, is no plaything. It holds an entire ore-rich asteroid with an already labyrinthine mine inside, possibly still having murderous illegal minedroids and a security force. But the flyland's former owner is also sending poison-gas-spewing spiderobots to ferret out and kill refugees. You have to save the refugees from everything this insane trillionaire has on the flyland, inside and outside the mine!
