PHOJET is a well established multi-purpose Monte-Carlo generator, focused towards the simulation of minimum bias, diffractive and forward phenomena. It is relying on the ideas of Regge-Theory and the topological expansion of QCD. Multi parton interactions evolve naturally from the Eikonal structure of scattering amplitudes. Although the program is still widely applied in high-energy physics and various technical contexts, it has not received updates or tuning since 2001. Latest measurements at high energies show that simulated multiplicity distributions do not properly describe experimental data and that adjustments to the model parameters have become necessary. In this talk, we will present the recent development status. We hope to shed light on the limitations of the involved Eikonal picture and we will present ideas for the upcoming version.
