Despite mounting evidence that astrophysical dark matter exists in the Universe, its fundamental nature remains unknown. In this paper, we present the prospects to detect and identify dark matter particles through the observation of very-high-energy ($\gtrsim$ TeV) gamma-rays coming from the annihilation or decay of these particles in the Galactic halo. The observation of the the Galactic Center and a large fraction of the halo by a future wide field-of-view gamma-ray observatory located in the southern hemisphere would reach unprecedented sensitivity to dark matter particles in the mass range of $\sim$500 GeV to $\sim$2 PeV. Combined with other gamma-ray observatories (present and future) a thermal relic annihilation cross-section could be probed for all particle masses from $\sim$80 TeV down to the GeV range in most annihilation channels.
