Only problem is that you just mentioned they died and he would give you a reward upon their Second deathVolkonski said:I suppose grandmaster could tie the super infected into a US army quest. Something like "Alpha squad went missing X weeks/months ago, we've tasked you and whomever you deem fit to accompany you to go find them. *Insert potential award here*". Also perhaps upon finding and eliminating the super infected you find a cache of weapons and supplies which you can either hoard for yourself or give to your faction.
