== Mobility Systems ==
Shells are designed with a wide-range of propulsion systems, and are sometimes built for a specific environment/gravity. Some synthmorphs may have multiple mobility systems. Many such systems are retractable, meaning they can be folded away into the shell’s frame.

'''Hopper:''' Hoppers have two or more legs designed to propel the morph forward or up, much like a frog or grasshopper. '''[Moderate]'''

'''Hovercraft:'''The shell uses an impeller to blast a cushion of high-pressure air off the surface below, repelling the frame off the ground (modern hovercraft do not use rubber skirts). Most hovercraft travel a meter or so above the ground, but can temporarily levitate themselves higher for short periods. '''[Low]'''

'''Internal Rocket:''' This miniature metallic hydrogen rocket is specifically designed for low thrust. It provides an acceleration of up to 0.25 g, allowing the morph to take off and land on all moons and other small bodies in the solar system. This engine can operate for a total of one and a half hours before it requires refueling. Both the sundiver and courier are considered to have this enhancement. '''[Moderate]'''

'''Ionic:''' The shell uses principles of magnetohydrodynamics to levitate and fly, by ionizing surrounding air into plasma to create lift and momentum. The shell is also spun for stability. This system does not work in vacuum, but an underwater version uses the same mechanics for propulsion in liquid environments. '''[High]'''

'''Microlight:''' Popular in low-grav and microgravity environments, microlights encompass several types of ultralight or lighter-than-air systems, such as powered paragliders, autogyros, balloons, aerostats, and blimps. These systems do not work in vacuum. '''[Low]'''

'''Roller:''' Only for circular shells, this system allows the synthmorph to roll like a ball. The shell rolls around an interior axle, propelled by a motor-driven pendulum. '''[Moderate]'''

'''Rotorcraft:''' Rotating blades create lift, allowing the shell to move and hover like a helicopter. Most models use tilt-rotors or tilt-wings so that the rotor blades may be moved forward (for faster propeller-like propulsion) and for better maneuverability in zero-G. This system does not work in vacuum. '''[Low]'''
'''Snake:''' Commonly used by slitheroids, these shells use lateral undulation, flexing their body from left to right and waving their frame forward. Such shells may also use sidewinding or a concertina motion (straightening forward, then retracting the rear) to move. They also featured gyroscope stabilization so that they may circle into a hoop and roll like a wheel. '''[Moderate]'''

'''Submarine:''' Designed for undersea mobility, submarine shells use propellers or pumpjets to push through water. '''[Moderate]'''

'''Tracked:''' Tracked shells use smart rotating treads to work their way across surfaces that would bog down other ground vehicles. They can prop themselves up in order to overcome taller obstacles or to lay themselves down to bridge across a ditch or crevice. '''[Low]'''

'''Thrust Vector:''' These shells use either turbofans or turbojets to create atmospheric lift with a set of wings. The engines may be maneuvered to point and generate thrust in different directions for vertical takeoffs/landings and better maneuverability in zero-G. '''[Moderate]'''

'''Walker:''' Walkers use two or more limbs to walk or crawl across a surface. Many use grip pads or magnetic systems to stick to surfaces. '''[Low]'''

'''Wheeled:''' Most wheeled shells feature smart spokes that allow the wheels to conform their shape to obstacles and even climb stairs. Some low-grav shells feature puncture-resistant and self-repairing compressed-gas tires. '''[Low]'''

'''Winged:''' Primarily used by smaller shells, this system of four independently-controlled wings allows the shell to hover or move rapidly in any direction. '''[Low]'''
