The superparticle models in superspace as well as in supertwistor space are reviewed. A new D=4 massless model is presented realizing dynamically the D=4 supersymmetry with six central charges. The model contains 3 kappa-symmetries providing BPS configuration preserving 3/4 of target space supersymmetries. The generalization to higher dimensions, in particular D=10 and D=11, is outlined.
