Billionare inventor Tony Stark has created the War Machine, a weapon of such destructive power that its single usage has prompted its shocked creator into vowing to never again manufacture munitions. This means that the awesome instrument of lethal force known as the MPI-2100 mobile infantry suit will be put on ice. While Stark feels that this concludes the subject, it is in fact merely the beginning. For the terrorist organizations known as Hydra and A.I.M. now crave the deadly technology. And when the super-spy agency called S.H.I.E.L.D. gets involved, the stage is set for a global conflict that could snuff out millions of lives!
