Echelle spectroscopy has been carried out towards a sample region of the halo of the giant H ii region 30 Doradus in the Large Magellanic Cloud. These new kinematical data are amongst the most sensitive yet obtained for this nebula and reveal a wealth of faint, complex high-speed features. These are interpreted in terms of localized 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.
