  Dark matter candidates such as weakly-interacting massive particles are
predicted to annihilate or decay into Standard Model particles leaving behind
distinctive signatures in gamma rays, neutrinos, positrons, antiprotons, or
even anti-nuclei. Indirect dark matter searches, and in particular those based
on gamma-ray observations and cosmic ray measurements could detect such
signatures. Here we review the strengths and limitations of this approach and
look into the future of indirect dark matter searches.
