We propose a dedicated search strategy for detecting four top quarks at the LHC at 13 TeV energies. We focus exclusively on the same-sign dilepton decay channel. The strategy is primarily based on a high b-tagging working point and a dynamical isolation cone for leptons. Our analysis also includes reducible backgrounds with electron charge flip mis-identifications and fake leptons. We apply the strategy to 4-top production in the SM and in non-resonant new physics scenarios. We argue that the LHC should find strong evidence for SM (or possibly BSM) 4-top production in run-II at higher luminosities.
