I am trying to get the DFA (Death From Above) kills achievement for SR4.
I think the best spot for other superpower/weapon kill grinding is in E.T.D. DLC, mission 2 specifically. However, the DFA superpower is not available during that mission.
What is the best (selection criteria = most kills per second, ease of setup, possibly repeatable) spot(s) to grind out the DFA kills achievement/challenge? I am near the end of the game, so using non-repeatable missions are not preferred, but I am still interested in knowing about them.
