The Damysos Gravity Control system is a device that enables a heavier than air object to overcome gravity and achieve controllable weightlessness in earth atmosphere. In 2131 these devices were uncommon and restricted to experimental machines such as a few ES.W.A.T. Landmate units, and some prototype cars. By 2133, the timeframe of Ex Machina, it had come to replace most winged aircrafts and had been fitted to nearly every Landmate in the ES.W.A.T. fleet.
