DESCRIPTION:Recent analyses of the publicly available Fermi-LAT gamma-ray 
 data find a line at\n~130 GeV coming from the vicinity of the galactic cen
 tre. This striking signal is\nconsistent with that from particle dark matt
 er annihilating into a two-body final\nstate containing a photon. In this 
 talk\, I review the experimental evidence for the\nline and outline the im
 plications for neutralino dark matter. Fitting the line while\nremaining c
 onsistent with other constraints will lead us to consider singlet\nextensi
 ons of the MSSM with a rich spectrum of light neutralinos and charginos. I
 \ndiscuss future characteristic phenomenological signatures of this scenar
 io at direct\nand indirect detection experiments as well as the LHC.
