The Large Hadron Collider (LHC) has been producing proton-proton collisions at a centre-of-mass energy of 13 TeV since 2015. No new particles have been discovered in this time. The absence of obvious evidence of a new particle, coupled with astrophysical measurements that indicate the existence of non-baryonic dark matter, motivate the search for the production of dark matter particles at the LHC in all possible channels and with increasingly sophisticated methods. I will illustrate this with a tour of three different dark matter searches with 13 TeV data. These searches involve looking for dark matter particles indirectly through a measurement of the missing transverse momentum. The large energy of the LHC motivates scenarios in which dark matter couples to the Standard Model sector through a mediator particle. The dark matter signal models and search strategies are discussed.
