  Echelle spectroscopy has been carried out towards a sample region of the halo
of the giant HII region 30 Doradus in the Large Magellanic Cloud. This new
kinematical data is the amongst the most sensitive yet obtained for this nebula
and reveals a wealth of faint, complex high speed features. These are
interpreted in terms of localised shells due to individual stellar winds and
supernova explosions, and collections of discrete knots of emission that still
retain the velocity pattern of the giant shells from which they fragmented. The
high speed velocity features may trace the base of the superwind that emanates
from the 30 Doradus starburst, distributed around the super star cluster R136.
