How good is a gatling gun against the Mastermind? I'm asking this because I'm going up against her with one (and a tac shotgun, agility-modded RL, laser rifle with one magazine of ammo, with tac boots and agility-modded blue armor). I've got plenty of ammo but only around two medkits. I've utilized running and dodging so far in this game to great effect (as evidenced by the fact that I made it to the final boss in the first place). And no, I don't have a nuke. Any advice you guys might have for me?
