The recent claims of a gamma-ray line in the Galactic center at 130 GeV has generated excitement, not least because it could be a signal of dark matter annihilation. I will summarize the current state of the observations of the Galactic Center, clusters, and unassociated halo objects, and speculate about models of particle dark matter that could explain the data.
