When SUSY is broken in multiple hidden sectors, there are multiple light goldstini, one of which can comprise most of the dark matter in the universe. The goldstino dark matter is generically unstable and will decay to the gravitino on cosmological time scales. I will discuss ongoing work on the novel possibility of a tree-level two-body decay to a single photon and a gravitino, which can occur with substantial branching fraction, producing a striking indirect detection signal for weak scale (or lighter) goldstini dark matter.
