Shield

Shields are a defensive asset, used to stop molecules travelling at speeds higher then the maximum set amount. As such, they are used for protecting all manners of objects from incoming projectiles, and even air. They work using the same effect as space-folding, using the Holtzman Effect to repell molecules. It is important to note tho, that shields are a very dangerous thing to use on the planet of Arrakis, because they attract worms. This makes ranged weapons a viable option while on Arrakis, despite the fact that in the rest of the imperium, they are rendundant.

Personal shields

Personal shields are a big part of both worlds of Dune and Dune: Awakening. Personal shields are used in combat since their invention, and force most of the Imperium to restrict to melee weapons for warfare, as they stop any fast moving projectiles, and render lasguns too dangerous to use, as they cause a pseudo-nuclear explosion. This reaction will not be a part of Dune: Awakening, as lasguns cannot be aimed at shields at all. The combat in Dune: Awakening will feature melee as one of its core combined arms elements, so shields will naturally be a very important part of combat, "forcing" players into melee to fight effectively. The downsides of using shields include attracting worms at a fast pace and having to watch your shield power level

Vehicular shields

Vehicles in the world of Dune have shields also. This seems to be the case of Dune: Awakening as well. It is currently unknown how shield - weapon interaction works with vehicles in Dune: Awakening.

Base shields

Shields are used to protect bases too, in both the book and game worlds. Visually, shields are only seen between the doorways and similar openings at the outskirts of player bases. Shields will (probably) make bases unraidable, or make it so its hard to do so. Shields will also need to be powered to help against possible base degradation and eventual demise.
