The continued increase in computing resources and the recent and ongoing development of sophisticated multidimensional, multi-frequency radiation-hydrodynamic codes is bringing core collapse supernova modeling into a new era. In addition to the classical constraints of gross nucleosynthetic yields, neutron star and black hole formation, explosion energies and neutrino signals, it is now becoming possible to ask that models reproduce additional observables such as pulsar kicks, small and large scale asymmetries in the neutrino ejecta, the mixing and inversion of heavy elements in the ejecta, and, when and if they are detected, gravitational wave signals. I will report on the state of the art in core collapse supernova modeling and discuss these additional constraints and the efforts made so far to reproduce them. After nearly 40 years the supernova explosion mechanism remains illusory. I will discuss how multidimensional modeling is enabling us to explore the role of potentially important additional phenomena in the mechanism, such as fluid instabilities, rotation, asymmetric neutrino radiation, and magnetic fields.
