Abstract
Direct observations of cosmic photon spectra from neutralino annihilation at energies above EGRET data might reveal the presence of dark matter in the Universe. Calculations of the rates for the continuum γ channel are reviewed together with the large theoretical uncertainties associated to a number of possible supersymmetric scenarios and different halo models. From an experimental point of view, a very selective rejection of the abundant cosmic ray background is a key issue.
