A precise quantitative description of particle collisions at existing and future high energy colliders requires the computation of full matrix elements for multi-particle final states. AMEGIC++ - A Matrix Element Generator In C++ will be presented. It has been designed to automatically compute arbitrary tree level matrix elements within the Standard Model and some popular extensions, i.e. the MSSM and the ADD model of large extra dimensions. As a part of the full event generator framework SHERPA it allows studies for a huge variety of signals for the physics of SM and beyond, as well as for the background. The helicity formalism which is used for the internal prescription of feynman amplitudes and further strategies to deal with a huge number of contribution amplitudes will be sketched. Some recent results to demonstrate the capabilities of AMEGIC will be presented.
