Mech flight is rarely elegant. The movement of these heavy machines is heavy and inertial. No pilot would wax poetic about the sublime handling characteristics of a chassis in flight – most would equate it with steering a rock as it plummets to the earth. Mechs beat down gravity for brief moments with raw output. Flight systems generally consist of additional thrusters configured around hardpoints on the chassis, powered by an additional power plant, that fire in rapid succession to propel a mech through the air.

While most systems only provide sufficient thrust for momentary flight – just enough to clear an obstacle – more advanced systems can sustain medium or longterm flight. GMS’s extra-vehicular activity (EVA) system uses forced air to keep the chassis stable and provide a small amount of additional mobility in zero gravity and aquatic environments. For atmospheric flight, GMS (and many other manufacturers) offer hard-burn impulse thrusters to generate a serviceable level of thrust and maneuverability.
