  This paper is devoted to the quantization of the second-ilk superparticle
using the Batalin-Vilkovisky method. We show the full structure of the master
action. By imposing gauge conditions on the gauge fields rather than on
coordinates we find a gauge-fixed quantum action which is free. The structure
of the BRST charge is exhibited and the BRST cohomology yields the same
physical spectrum as the light- cone quantization of the usual superparticle.
