An advance form of FTL, it makes use of subspace physics. It is one of the fastest forms of transportation, being able to get around a galaxy in a few hours.
While it is called the 'Hyper' Drive, it actually only creates a tunnel through subspace. Usually a makeshift pocket dimension is being used to connect one point to the other, with the craft flying through it. Their use is often marked by Hyper Space Windows', large luminous portals that mark the journey's beginning and end. There are also other types that simply 'speed' of simply entering this other dimension.
