Presupernova evolution, explosion and nucleosynthesis of rotating
massive stars at various metallicities

I will present an overview of the evolution of massive stars from the
pre main sequence phase up to the onset of the iron core collapse,
their hydrostatic and explosive nucleosynthesis and their final fate.
The models extend in mass between 13 and 80 Msun, have initial
metallicities corresponding to [Fe/H]=0,-1,-2,-3 and have initial
rotation velocities corresponding to v=0, 150 and 300 km/s.
