Through the first seven K2 fields, 16 pulsating subdwarf B stars have been discovered. Most of these stars have yet to be fully analyzed and this poster will review the current status of our work. So far we have discovered several new short-period pulsators, which were lacking in K1; an ellipsoidal variable with no indications of frequency multiplets, even though its orientation and short binary period are well-suited for their detection; and asymptotic period spacings which are filling in evolutionary parameter space.
