The search for new comparably light (well below the electroweak scale) feeblyinteracting particles is an exciting possibility to explain some mysteriousphenomena in physics, among them the origin of Dark Matter. The sensitivitystudy through detailed simulation of projected experiments is a key point inestimating their potential for discovery.  Several years ago we created the DMG4 package for the simulation of DM (DarkMatter) particles in fixed target experiments. The natural approach is tointegrate this simulation into the same program that performs the fullsimulation of particles in the experiment setup. The Geant4 toolkit frameworkwas chosen as the most popular and versatile solution nowadays.  The simulation of DM particles production by this package accommodatesseveral possible scenarios, employing electron, muon or photon beams andinvolving various mediators, such as vector, axial vector, scalar,pseudoscalar, or spin 2 particles. The bremsstrahlung, annihilation orPrimakoff processes can be simulated.  The package DMG4 contains a subpackage DarkMatter with cross section methodsweakly connected to Geant4. It can be used in different frameworks.  In this paper, we present the latest developments of the package, such asextending the list of possible mediator particle types, refining formulas forthe simulation and extending the mediator mass range. The user interface isalso made more flexible and convenient.  In this work, we also demonstrate the usage of the package, the improvementsin the simulation accuracy and some cross check validations.
