With the recent results of large hybrid air-shower experiments, it is clear that the simulations of the hadronic interactions are not reliable enough to obtain a consistent description of the observations. Even the mostrecentmodelstunedafterthefirstrunoftheLHCshowsignificantdiscrepancywithair-showerdata. Since then many more data have been collected at the LHC and at lower energies at the SPS which are not necessarily well described by these models. So before claiming any explanation involving new physics, it is necessary to have a model which can actually describe accelerator data in a very detailed way. That is the goal of EPOS 3, to understand both soft and hard particle production not only in light systems like proton-proton interactions but in heavy ions too. The latest results of the model will be presented and in particular the correlations between various observables which are very important to understand the real physical processes.
