A generalized BRST formalism is developed and used to study the quantization of the Siegel superparticle. The method provides an off-shell nilpotent BRST symmetry of the gauge-fixed, quantum action. The construction relies on the structure of the classical gauge algebra, and is realized by introducing a set of auxiliary, nonphysical variables. The elimination of these variables reduces the theory to the Batalin-Vilkovisky form.
