The unitarity method is a key part of the set of on-shell methods for calculating gauge-theory amplitudes both analytically and numerically. These methods have been used successfully to obtain the one-loop amplitudes needed for a variety of cutting-edge high-multiplicity next-to-leading order calculations for LHC physics. They have been applied both to analytic calculations, and in the framework of numerical codes such as BlackHat. In this talk, I discuss the first steps in extending maximal unitarity to a computation of two loop amplitudes, needed for precision LHC calculations.
