  We study an equivariant extension of the Batalin-Vilkovisky formalism for
quantizing gauge theories. Namely, we introduce a general framework to
encompass failures of the quantum master equation, and we apply it to the
natural equivariant extension of AKSZ solutions of the classical master
equation (CME). As examples of the construction, we recover the equivariant
extension of supersymmetric Yang-Mills in 2d and of Donaldson-Witten theory.
