The advent of new accelerators technologies, like the use of intense and stored antiprotons beams, will set an inflection point in what we know today as Modern Physics. The outstanding large production probability in antiproton collisions will open the floodgates for a series of new studies of systems which contain two or even more units of strangeness at the PANDA experiment at the FAIR facility. For the first time, high-resolution $\gamma$-spectroscopy of doubly strange $\Lambda\Lambda$-hypernuclei will be performed, thus complementing measurements of ground-state decays of $\Lambda\Lambda$-hypernuclei at J-PARC or possible decays of particle unstable hypernuclei in heavy-ion reactions. High-resolution spectroscopy of multistrange $\Xi^{-}$-atoms will be feasible and even the production of $\Omega^{-}$-atoms will be within reach. The latter might open the door to the $|S|=3$ world in strangeness nuclear physics, by the study of the hadronic $\Omega^{-}$-nucleus interaction. For the first time it will be possible to study the behaviour of $\overline{\Xi}^{+}$ in nuclear systems under well-controlled conditions.
