For interpreting DM search results at the LHC the simplified mediator-based dark matter models are used, that allow to minimize the number of new particles and model parameters in consideration. In particular, only one spin-0 or spin-1 mediator and one DM particle $\chi$ assumed to be a fermion are introduced. Also s-channel processes are mainly considered in the simplest case.
Several searches are presented for DM signals within the simplified mediator-based models with an emphasis on fully visible signatures (heavy resonances) and MET signatures with good model sensitivity, especially to 2HDM+\zv~ and 2HDM+$a$ model parameters.
