Atmoflyers are the fixed-wing aircraft used on planets too primitive to have developed gravitic technology. Faster and simpler to maintain than comparable helicopters, they can also carry more cargo on most worlds. The need for clear, hard terrain for landing and take-off limit their use on some rugged worlds. The model here is meant to represent a small personal jet.
Vehicle Weaponry
Most vehicles larger than a motorcycle or hovercycle can mount some kind of integral weapon. Atmoflyers can mount two.
Heavy weapons take up more space than ordinary ranged weapons, and each such system takes up the space of two lesser guns.
Every weapon requires its own gunner, and all mounted weapons use Shoot as the firing skill, though the GM might allow Pilot to be used for a nose-mounted weapon aimed by the operator.
