I will present the latest study on supersymmetry from the GAMBIT collaboration, where we have investigated the combined collider constraints on the MSSM "electroweakinos" (neutralinos and charginos), assuming that other SUSY particles are decoupled. Using GAMBIT, we have performed a large-scale global fit where we incorporate simulations of recent ATLAS and CMS SUSY searches, in addition to constraints from SUSY searches at LEP and the invisible decay widths of the Z and Higgs bosons. When working in the general four-dimensional parameter space of the MSSM electroweakino sector, we find that the data do not robustly exclude any range of electroweakino masses. Further, due to several small excesses in the LHC data, we find a preference for a scenario where all the electroweakinos are lighter than ~500 GeV.
