Hovertech

Hovertech is an extremely common form of technology, a part of Standard Asset Equipment for vehicles, often an essential part.

Capabilities
Hovertech, at its most basic function, keeps an asset suspended in the air. It is usually seen in the form of a "lift," usually on the underside of assets, to keep them in the air. However, the "projector" variant also exists, which instead lifts up other objects. However, this form of tech only works within gravity wells, such as on planetside surfaces, as they must have a form of mass to push against. On a standard Earth-like planet, hovertech can enable a vehicle to scale up to the upper atmosphere before beginning to fail, although spacecraft will be able to make up for this with their standard thrusters. Large cruisers, especially capital ships, cannot remain in the atmosphere without the use of hovertech, and neither can large floating cities, such as those seen on New Earth's moons. Especially large ships cannot even be supported by their own landing gear, often requiring hovertech to stay upright. Scaled-up versions of this technology often become tractor beams or gravity well generators.

Background
Hovertech was developed before the Old Titanian Empire, meant to allow hoverlanes of flying cars to clear up surface-based roads, and to make aerospace travel more effective. It remained a staple of advanced and space-faring civilizations ever since.

Variants
Lift: The most common variant, seen on the undersides of hovercars and spacecraft. They can also be seen on smaller scales, such as on robots, chairs, cots, and a multitude of other small devices. They often come in the form of vent lifts or lev-plates.

Projector: A rarer variant, used to keep an external object up in the air. This is sometimes seen holding up floating cities or structures suspended over dangerous locations, such as cliffs, magma, or other hazards.

Plas-Graviton tech: Plas-Graviton tech is a highly advanced form of hovertech developed and utilized by the Military. Resembling a sort of reactionless drive, the functions of plas-graviton tech are classified and relatively unknown, but are known to manipulate a plasma-like form of particles known as gravitons, which achieved the breakthrough of not needing mass to push against, simply propelling the user in any given direction. This technology, while highly versatile and maneuverable, is only available at small scales, unable to replace standard thrusters, and often used in tandem with other thruster gear. Due to its size, it is used on single organic units that require more mobility than standard thrusters and hovertech can grant, such as the Mark 2 Astro Marines. Plas-grav tech is incredibly expensive and difficult to manufacture, first being used on the Military Multi-Phase Suit, thus not allowing it to fully replace all unit-sized thruster tech, leading to only the elite Astro Marines and MPS units receiving said technology.
