In 2015, the LHC center-of-mass energy increased from 8 TeV to 13 TeV following a two-year technical stop of the LHC. This energy increase dramatically enhances the potential for discovery of massive new particles at CMS and ATLAS. Of all models predicting new particles at the LHC, supersymmetry (SUSY) garners considerable interest because it can simultaneously explain dark matter, stabilize the Higgs mass, and allow more precise unification of the fundamental interactions. Initial SUSY searches are designed to be general and robust to maximize the chance for rapid discovery with a newly commissioned detector. I will present results from these first inclusive SUSY searches in final states characterized by the presence of several hadronic jets and large missing transverse momentum potentially associated with undetected SUSY particles.
