For all IB purchases and general glimmer farmers. Fast Glimmer Farming. Select the exclusion zone mission on mars With heroic mod on. Open the gate turn on your resupply codes and kill all the cabal except one cabal major/ultra( nine of them come with the second drop ship) Let him kill you and repeat as you need. Also good for kill 10 cabal majors. I think you have to do it with a heroic mod on to get the 9 of them. But it's like lvl 17 or 19 so it's still pretty easy.
