"You have SO many layers of defense in this game to try and keep you going. First, you have SHIELDS. This game takes place in 20,000 A.D. Who would've thought we might invent a shielding system for our ships by then?"

User can create a shield, wall, barrier, dome, or a field formed from energy, elements, the environment, or by manipulating smaller items to form a greater whole. The shields typically take on a dome/spherical or flat shape centered on or around the user. Some users can generate a thin force-field around their body. Force-Field are capable to blocking/nullifying attacks (including physical attacks) or even reflecting them. Force-Fields are also used as containment to imprison others.
